A plank AB 3. 0m long weighs 20kg and with it's centre of gravity 2. 0m from the end A. It rests on two supports at C and D. I) compute the values of the reaction forces R1 and R2 at C and D. Ii) how far from D and in which side of it must a mass of 24kg be placed on the plane so as to make the reaction equal? what are their values ? iii) without this 24kg ,what vertical force applied at B will just lift the plank clear of D ? what is then the reaction at C
Answers
A vertical force of approximately 196.2 N applied at B will just lift the plank clear of D. When this happens, the reaction force at C will be zero, and the entire weight of the plank will be supported by the reaction force at D, which is 157.5 N as calculated earlier.
To solve this problem, we can use the principles of statics, which state that the sum of the forces and moments acting on a rigid body must be zero for it to be in equilibrium.
I) To find the values of the reaction forces R1 and R2 at C and D, we can consider the forces acting on the plank. There are three forces acting on the plank: its weight acting downwards at its center of gravity (CG), the reaction force R1 at C, and the reaction force R2 at D. Since the plank is in equilibrium, the sum of the forces acting on it must be zero. Therefore, we can write:
ΣF = 0
where ΣF is the sum of the forces. In this case, it is equal to the sum of the components of the forces in the vertical direction, which is:
R1 + R2 - W = 0
where W is the weight of the plank. Substituting the given values, we get:
R1 + R2 - 20g = 0
where g is the acceleration due to gravity. We also know that the plank is in static equilibrium, which means that the sum of the moments of the forces acting on it about any point must be zero. We can choose point D as the reference point, and write:
ΣM = 0
where ΣM is the sum of the moments of the forces about point D. In this case, it is equal to the sum of the moments of the weight and the reaction force R1 about point D, which is:
R1 x 2 - 20g x 1.5 = 0
Solving the two equations simultaneously, we get:
R1 = 22.5g ≈ 220.5 N
R2 = 20g - R1 = 157.5 N
Therefore, the values of the reaction forces R1 and R2 at C and D are approximately 220.5 N and 157.5 N, respectively.
II) To find how far from D and on which side of it the 24kg mass should be placed so as to make the reaction forces equal, we can use the principle of moments again. Let x be the distance from D to the 24kg mass, and let R be the reaction force at both C and D. Then, we can write:
ΣM = 0
where ΣM is the sum of the moments of the forces about point D. In this case, it is equal to the sum of the moments of the weight of the plank, the weight of the 24kg mass, and the reaction force R1 about point D, which is:
R x 3 - 20g x 1.5 - 24g(x + 2) = 0
Solving for x, we get:
x = 0.75 m
Therefore, the 24kg mass should be placed 0.75 m from D, on the opposite side of R2.
To find the value of R, we can use the principle of forces, which states that the sum of the forces acting on a body must be zero if it is in equilibrium. In this case, it is equal to:
R + 24g - R2 = 0
Substituting the given values, we get:
R = 115.5g ≈ 1131.9 N
Therefore, the value of the reaction force at both C and D when the 24kg mass is placed 0.75m from D is approximately 1131.9 N.
III) To find the vertical force applied at B that will just lift the plank clear of D, we can consider the forces acting on the plank when it is about to lift off. In this case, the only force acting on the plank is the vertical force applied at B, which we can call F. We can write the equation of forces in the vertical direction:
ΣF = 0
where ΣF is the sum of the forces acting on the plank. In this case, it is equal to the sum of the components of the force F and the weight of the plank in the vertical direction, which is:
F - 20g = 0
Solving for F, we get:
F = 20g ≈ 196.2 N

in challenge example 11.11, the steel ball is released at an angle of 45 degrees, but at the end of the process only reaches an angle of 19 degrees. why didn't the steel ball reach the full 45 degrees?
Answers
The steel ball in Challenge example 11.11 did not reach the full 45 degrees because of the air resistance.
When an object moves through the air, it has to overcome the force of air resistance, which opposes the motion of the object. This force is proportional to the surface area of the object and the speed at which it moves through the air. Therefore, the faster an object moves through the air, the more air resistance it experiences.
In the case of Challenge example 11.11, the steel ball was released at an angle of 45 degrees, but as it moved through the air, it experienced air resistance, which slowed it down. As a result, it did not reach the full 45 degrees and only reached an angle of 19 degrees. This is because the force of air resistance acting on the ball increased as it moved through the air, and this force eventually became greater than the force of gravity acting on the ball.
As a result, the ball slowed down and did not reach the full 45 degrees.

A rocket of mass 5kg is travelling horizontally with a speed of 200m/s when it explodes into two parts.
one part of mass 3kg continues in the original direction with a speed of 100m/s and the other part continues in the same direction.
*Calculate the unknown speed of the other part*
(please solve with steps + explanation)
Answers
Answer:
350 m/s
Explanation:
Before the explosion, the rocket's momentum is given by:
p = m*v where
p = momentum
m = mass of the rocket
v = velocity of the rocket
Given that the mass of the rocket is 5 kg and its velocity is 200 m/s, we can calculate the momentum as:
p = m*v = 5 kg * 200 m/s = 1000 kg·m/s
After the explosion, the momentum is conserved, which means the total momentum of the two parts is still 1000 kg·m/s. We can use this principle to solve for the velocity of the second part.
Let v1 be the velocity of the 3 kg part, and v2 be the velocity of the other part. Since they are both moving in the same direction, we can write:
p = m1v1 + m2v2
where m1 = 3 kg is the mass of the first part, and m2 is the mass of the second part.
Substituting the known values, we get:
1000 kg·m/s = 3 kg * 100 m/s + m2 * v2
Solving for v2, we get:
v2 = (1000 kg·m/s - 300 kg·m/s) / m2
v2 = 700 kg·m/s / m2
We still need to find the mass of the second part. Since the rocket initially had a mass of 5 kg, and one part has a mass of 3 kg, the other part must have a mass of:
m2 = 5 kg - 3 kg = 2 kg
Substituting this into the equation for v2, we get:
v2 = 700 kg·m/s / 2 kg
v2 = 350 m/s
Therefore, the unknown speed of the other part is 350 m/s.
what is mechanical energy
Answers
Explanation:
In physical sciences, mechanical energy is the sum of potential energy and kinetic energy. It is the macroscopic energy associated with a system. The principle of conservation of mechanical energy states that if an isolated system is subject only to conservative forces, then the mechanical energy is constant. If an object moves in the opposite direction of a conservative net force, the potential energy will increase; and if the speed (not the velocity) of the object changes, the kinetic energy of the object also changes. In all real systems, however, nonconservative forces, such as frictional forces, will be present, but if they are of negligible magnitude, the mechanical energy changes little and its conservation is a useful approximation. In elastic collisions, the kinetic energy is conserved, but in inelastic collisions some mechanical energy may be converted into thermal energy. The equivalence between lost mechanical energy (dissipation) and an increase in temperature was discovered by James Prescott Joule.

Two point charges are placed at the following points on the x-axis. +2.0 C at
×=0, -3.0.C at 0.40m. Find the electric field strength at 1.20m?
Answers
The electric field strength at a distance of 1.20 m on the x-axis is -1.5 × 10⁴ N/C.
To find the electric field strength at a distance 1.20 m on the x-axis, we can use Coulomb's law:
\($$F=k\frac{q_1q_2}{r^2}$$\)
where F is the force between two charges, q1 and q2 are the magnitudes of the charges, r is the distance between the charges, and k is the Coulomb constant.For a single point charge q located at the origin of the x-axis, the electric field E at a distance r is given by:
\($$E=\frac{kq}{r^2}$$\) where k is the Coulomb constant.
So, let's calculate the electric field due to each charge separately and then add them up:
For the +2.0 C charge at x = 0, the electric field at a distance of 1.20 m is:\($$E_1=\frac{kq_1}{r^2}=\frac{(9\times10^9)(2.0)}{(1.2)^2}N/C$$\)
For the -3.0 C charge at x = 0.40 m, the electric field at a distance of 1.20 m is:
\($$E_2=\frac{kq_2}{r^2}\)
\(=\frac{(9\times10^9)(-3.0)}{(1.20-0.40)^2}N/C$$\)
The negative sign indicates that the direction of the electric field is opposite to that of the positive charge at x = 0.
To find the net electric field, we add the two electric fields\(:$$E_{net}=E_1+E_2$$\)
Substituting the values of E1 and E2:
\($$E_{net}=\frac{(9\times10^9)(2.0)}{(1.2)^2}-\frac{(9\times10^9)(3.0)}{(0.8)^2}N/C$$E\)
net comes out to be -1.5×10⁴ N/C.
Therefore, the electric field strength at a distance of 1.20 m on the x-axis is -1.5 × 10⁴ N/C.

which color of visible light would have the least energy? which would have the most energy? how do you know?
Answers
The color of visible light that would have the least energy is red. On the other hand, the color of visible light that would have the most energy is violet.
This is because red light has the longest wavelength and the lowest frequency out of all the colors in the visible spectrum. Violet light has the shortest wavelength and the highest frequency out of all the colors in the visible spectrum.
This relationship between wavelength, frequency, and energy can be explained by the relationship between electromagnetic waves and energy. All electromagnetic waves, including visible light, have a certain amount of energy that is proportional to their frequency. The higher the frequency, the more energy the wave has.

If a pendulum system was established on the Moon, how long would the pendulum be to obtain a period of 3.5 seconds
Answers
To establish a pendulum system on the Moon with a period of 3.5 seconds, the pendulum would need to have a length of approximately 1.11 meters.
A pendulum is a weight suspended from a pivot so that it can swing freely. When a pendulum is displaced to one side of its equilibrium position and then released, it will swing back and forth, and the motion will continue until friction (or drag) causes the oscillations to gradually dampen and come to a halt. The time it takes for one complete oscillation, or period, of a pendulum is determined by its length and the force of gravity on it.
In the case of a pendulum on the Moon, the period would be longer than it would be on Earth because the force of gravity is weaker on the Moon. To determine the length of the pendulum needed for a 3.5 second period on the Moon, we can use the following formula:
T = 2π√(L/g)
Where: T = period of the pendulum L = length of the pendulum g = acceleration due to gravity On the Moon, the acceleration due to gravity is about 1.6 m/s², so we can plug in the given period of 3.5 seconds and solve for the length :L = (T²g)/(4π²) = (3.5² × 1.6)/(4π²) ≈ 1.11 meters
Therefore, the pendulum would need to be approximately 1.11 meters long to achieve a period of 3.5 seconds on the Moon.

A ball with topspin rotates in the opposite direction as a ball with underspin. What would be the direction of the Magnus effect
on a ball with topspin? How do you think this would affect the ball’s motion?
Answers
The ball drops quicker as a result of the topspin, which might make it more challenging for the opponent to strike the ball at the appropriate moment. Topspin may be used to produce shots that are more difficult to return because of this.
What is Topspin and Underspin?Generally, The Magnus effect is caused by the difference in air pressure on the top and bottom of a spinning object.
On a ball with a topspin, the air pressure is greater on the top of the ball than on the bottom, which creates a lifting force that causes the ball to move upward.
This can cause the ball to have more height or to curve in a specific direction, making it more difficult for the opponent to return.
The topspin also causes the ball to drop faster than it would otherwise, which can make it more difficult for the opponent to hit the ball at the right time. This makes topspin a useful tool for making shots that are harder to return.

a = (vf - vi) /t
a = (10.0 m/s - 0 m/s) /2.4 s
a = (10.0 m/s) /2.4 s
a = 4.16 m/s²
What is acceleration?It is a physical quantity that indicates the variation of velocity as a function of time, it is expressed in units of distance per time squared e.g.: m/sec2 ; km/h2
