Question

A ball of mass m is released from rest relative to elevator at a height h1 above the floor

Answer 1

A ball is released from rest relative to the elevator at a distance h1 above the floor. The speed of the elevator at the time of ball release is v0. Determine the bounce height h2 of the ball (a) if v0 is constant and (b) if an upward elevator acceleration a = g/4 begins at the instant the ball is released. The coefficient of restitution for the impact is e.

Answer 2

For an object bouncing off a stationary object, such as a floor, coefficient of restitution, e=h′h−−√e=h′h

⇒⇒ The height to which it bounces h′=e2hh′=e2h

Similarly, after it rebounds for the nth time, the height to which it rises h′=e2nhh′=e2nh

Answer: e2nh
