10 6 P073 MIF My N A tennis ball of mass 57.0 g is held just above a basketball qf fall through a distance of 1.10 m, as shown in the figure below. aligned, both balls are released from rest at the same time, to (a) Find the magnitude of the downward velocity with which the basketball reaches the ground. 643 m/s (b) Assume that an elastic collision with the ground instantaneously reverses the velocity of the basketball while the two balls meet in an elastic collision. To what height does the tennis ball rebound? Find the relative velocties of the basketball and the tennis bal just before collision and then apply the appropriate conservation principles and rules for perfectly elastic collisions to find the tennis ball velocity and the height that the basketball reaches. m Need Help?
