A mass of M-kg rests on a frictionless ramp inclined at 30. A string with a linear mass density of =0.025" kg/m" is attached to the M-kg mass. The string passes over a frictionless pulley of negligible mass and is attached to a hanging mass (m). The system is in static equilibrium. A wave is induced on the string and travels up the ramp. (a) Show that the mass of M is equal to twice the mass of the hanging mass: M = 2m.(b) and at what wave speed does the wave travel up the string, if m = 5 kg?
