A piano (mass m=315kg)is being pushed up a frictionless ramp with a force with a magnitude of P=2020N that is parallel to the ramp.The ramp makes and angle of 28.3 degrees to horizontal Part (a) write an expression for the magnitude of the acceleration of the piano, in terms of the symbols in the problem statement, and g (9.80m/s^2). Part(b) what is the magnitude of the acceleration of the piano in m/s^2? Part(c) if the ramp is 3.73 m long and the piano started from rest. What is the speed in minutes per second of the piano when it reaches the top of the ramp
