A ball is dropped from a height, $h_1$, at Position A and rebounds to a lower height, $h_2$, at Position D as shown in the diagram below. Position B represents the location of the ball just before it lands and Position C is the location of the ball just after it leaves the ground. Assume the effect of air resistance on the ball is negligible.
