A tennis ball of mass 57.0 g is held just above a basketballof mass 590 g. With their centers vertically aligned, bothballs are released from rest at the same time, to fall through adistance of 2.00 m.
a) Find the magnitude of the downward velocity with which thebasketball reaches the ground.
b) Assume that an elastic collision with the ground instantaneouslyreverses the velocity of the basketball while the tennis ball isstill moving down. Next, the two balls meet in an elasticcollision. To what height does the tennis ballrebound?
