DR C H 5 0 m b 9m d e H 5 0 m 7 777777 7777 C1992M1 A ball of mass 9m is dropped from rest from a height H 5 0 meters above the ground as shown above on the left It undergoes a perfectly elastic collision with the ground and rebounds 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 as shown above on the right The clay blob which is descending collides with the ball 0 5 seconds later which is ascending Assume that g 10 m s that air resistance is negligible and that the collision process takes negligible time T a Determine the speed of the ball immediately before it hits the ground Determine the rebound speed of the ball immediately after it collides with the ground justify your answer Determine the height above the ground at which the clay ball collision takes place 9m Determine the speeds of the ball and the clay blob immediately before the collision If the ball and the clay blob stick together on impact what is the magnitude and direction of their velocity immediately after the collision
