A 10 kg block is allowed to slide down a frictional incline for a length of 10 m on an incline of 35. At the end of the ramp, the block slides off and falls 20 m to the ground below. The coefficient of kinetic friction between the incline and the block is .21. What is the acceleration of the block on the incline? Explain how energy is trans formed. What is the velocity at the end of the incline how much time is the block on the incline? How long is the block in the air?
what is the horizontal distance from the end of the incline to when the block stricks the ground?

What is the magnitude of the vertical component of its velocity as it strikes the ground.
The objects are then released from rest. Assuming that the particles never reach the pulley, and also that the particles do not rebound when they strike the ground.
How far below the release point is the center of mass of two stones at t = 550 ms? (Neither stone has yet reached the ground.)
