i. A ball of mass 57.0 g is held just above a of mass 590 g. With their centers vertically aligned, both balls are released from rest at the same time, to fall through a distance of 1.20 m. Assume that an elastic collision with the ground instantaneously reverses the velocity of the larger ball while the smaller ball is still moving down. Next, the two balls meet in an elastic collision. To what height does the smaller ball rebound
