When a car comes to a stop, the car’s brakes create a force that is in the opposite direction as the velocity vector.

A friction force is a type of force that opposes two surfaces that are in contact with each other.

According to Newton's first law of motion, an object at rest or uniform motion in a straight line will continue in that state unless it is acted upon by an external force. And the object will tend to move in the direction of the applied force.

So if a car's brake is applied, it will create a friction force that will oppose the motion of the car and by so doing, it will gradually bring the car to a complete stop.

The force created by the brake of the car is friction force and it is in opposite direction to the force of the car.

A) Torque exerted on the pivot point P by force F is: 17.02 Nm  B)  torque exerted on the pivot point P by force F at an angle of 56.3 degrees above the radial line is: 13.83 Nm.

Torque is a measure of the rotational force on any object around an axis or pivot point.

A) Torque = Force x Lever arm

Given force F is 51.2 N and the lever arm is 33.3 cm.

Lever arm = 33.3 cm = 0.333 m

Therefore, torque exerted on the pivot point P by the force F is:

Torque = 51.2 N x 0.333 m = 17.02 Nm

B) If the force F is applied at an angle of 56.3 degrees above the radial line,  Perpendicular force = Force x sin(angle)

Perpendicular force = 51.2 N x sin(56.3°) = 41.48 N

The lever arm is still 0.333 m. Therefore, torque exerted on the pivot point P by force F at an angle of 56.3 degrees above the radial line is:

Torque = Perpendicular force x Lever arm = 41.48 N x 0.333 m = 13.83 Nm.

Answer:

d

Explanation:

Answer:

30 m/s

Explanation:

v = u + at

given that,

v = 10 + ( 2 × 10)

v = 10 + 20

v = 30 m/s

Take into account that over any surface area, you can roll or slide. moreover, an object can remain in a position (on a sruface) because of the static friction.

Then, static, rolling and sliding frictions are present in the influence of a surface area.

Radius of rotation, r = \(mv^2\)/F = (3.0 kg)(5.0 \(m/s)^2\)/(8.0 N) = 9.375 m.

To find the radius of rotation for a rotating object with a mass of 3.0 kg and a force of 8.0 N acting upon it,

we can use the centripetal force formula:

F = \(mv^{2/r\). In this formula, F represents the force, m is the mass, v is the velocity, and r is the radius.

Given a mass of 3.0 kg, a force of 8.0 N, and a rotational speed of 5.0 m/s,

we can rearrange the formula to solve for the radius: r = \(mv^{2/F\).

Plugging in the given values,

we get r = (3.0 kg)(5.0 \(m/s)^2\)/(8.0 N) = 9.375 m.

Thus, the radius of rotation is 9.375 meters.

Based on Newton's first  and second law of motion most people would find it less painful to catch a flying baseball than a bowling ball flying at the same speed as the baseball because the mass of the baseball is smaller and will require smaller force to be stopped.

Newton's first law of motion first law of motion states that a body at rest or uniform motion in a straight line will continue in that path unless acted upon by an external force.

Newton's first law of motion is also called law of inertia because it depends on mass of the object.

An object with a greater mass will require greater force to be stopped or get moving.

Based on Newton's first law of motion most people would find it less painful to catch a flying baseball than a bowling ball flying at the same speed as the baseball because the mass of the baseball is smaller and will require smaller force to be stopped.

Also according to Newton's second law of motion, the force applied to an object is proportional to the product of mass and acceleration of the object. Thus, a baseball with smaller mass will require smaller force to be stopped.

Answer: Natural science can be divided into two main branches

Explanation:

life science and physical science. Life science is alternatively known as biology, and physical science is subdivided into branches: physics, chemistry, astronomy and Earth science.

Explanation:

The attatched figure shows the vector diagram for a force that has magnitude of 60 N and it is acting at an angle of 30° from the horizontal​.

When it is resolved, the horizontal and vertical components are given by :

\(F_x=F\cos\theta\\\\=60\times \cos30\\\\=51.96\ N\)

And

\(F_y=F\sin\theta\\\\=60\times \sin30\\\\=30\ N\)

Hence, this is the required solution.

The passenger is moving at a speed of 5.13 m/s relative to the water, with a direction of 38.1° north of east.

A quantity or phenomena with independent attributes for size and direction is called a vector. Another meaning of the term is the mathematical or geometrical representation of a quantity. Vectors can be found in nature as force, momentum, electromagnetic fields, weight, and velocity.

Let's think of the boat's velocity in relation to the water as vector B and the passenger's velocity in relation to the boat as vector P.

B = (3.97 m/s) cos(50°) i + (3.97 m/s) sin(50°) j

= 2.55 i + 3.07 j

P = (1.46 m/s) i

= 1.46 i

Adding these vectors, we get:

B + P = 2.55 i + 3.07 j + 1.46 i

= 4.01 i + 3.07 j

The magnitude of the velocity of the passenger relative to the water is the length of this vector:

|B + P| = sqrt[(4.01 m/s)^2 + (3.07 m/s)^2] = 5.13 m/s

The direction of the velocity of the passenger relative to the water is the angle this vector makes with the positive x-axis, measured counterclockwise from due east.

Current cannot flow uphill in any of the listed options: a light bulb, a battery, a flowing water conduit, or a resistor. Hence option E) is the correct answer.

Current cannot flow uphill in any of the listed options: a light bulb, a battery, a flowing water conduit, or a resistor. In an electrical circuit, current is the flow of electric charge carried by electrons. Current flows in a closed loop, typically from the positive terminal of a power source (such as a battery) through the circuit components and back to the negative terminal. A light bulb, battery, flowing water conduit, and resistor all have specific roles within a circuit, but none of them allow current to flow uphill. In a circuit, current always flows from a higher electric potential to a lower electric potential. This is known as the direction of conventional current flow. In the case of flowing water, water flows downhill due to gravity, following the path of least resistance. Similarly, in an electrical circuit, current flows along the path of least resistance, from higher voltage (electric potential) to lower voltage. Therefore, option E) is the correct answer current does not flow uphill in any of the mentioned options.

The correct answer is D. solids and liquids because their particles are arranged more closely together.

Answer:

the magnitude of the average contact force exerted on the leg is  3466.98 N

Explanation:

Given the data in the question;

Initial velocity of hand v₀ = 5.25 m/s

final velocity of hand v = 0 m/s

time interval t = 2.65 ms = 0.00265 s

mass of hand m = 1.75 kg

We calculate force on the hand F\(_{hand\)

using equation for impulse in momentum

F\(_{hand\) × t = m( v - v₀ )

we substitute

F\(_{hand\) × 0.00265  = 1.75( 0 - 5.25 )

F\(_{hand\) × 0.00265  = 1.75( - 5.25 )

F\(_{hand\) × 0.00265  = -9.1875

F\(_{hand\) = -9.1875 / 0.00265  

F\(_{hand\) = -3466.98 N

Next we determine force on the leg F\(_{leg\)

Using Newton's third law of motion

for every action, there is an equal opposite reaction;

so, F\(_{leg\) = - F\(_{hand\)

we substitute

F\(_{leg\) = - ( -3466.98 N )

F\(_{leg\) = 3466.98 N

Therefore, the magnitude of the average contact force exerted on the leg is  3466.98 N
