A 450g rubber ball is dropped from 2.0m above the floor. After the bounce, the ball only rises to a height of 1.5m above the floor.
A. Determine the change in momentum of the ball when it hits the floor and bounces up.
B. Calculate the amount of heat generated when the ball hits the floor.
C. Explain how momentum is conserved when the ball collides with the floor. (hint: either use motion equations or conservation of energy to determine the speed of the ball when it reaches the floor.)
