At the instant that the ball rebounds, a small blob of clay of mass m is released from rest from the original height H, directly above the ball. The clay blob, which is descending, eventually collides with the ball, which is ascending. Assume that g=10 m/s^2, that air resistance is negligible, and the collision process takes negligible time a ...
