As shown below, a block of mass ?1=2.50kg rests on a ramp of mass ?2=8.85kg. The ramp has an incline of ?=52.0°above the horizontal. The surface of the ramp is frictionless, and the ground on which the ramp rests is also frictionless. The ramp is not attached to the ground. The system is released from rest. (a) What is the magnitude of the acceleration of the ramp? (b) What static friction coefficient would be needed between the ramp and the floor in order to keep prevent the ramp from accelerating?
