A ball is hanging from a cord of negligible weight. A secondary ball with the same weight as the first ball is measured 3 m above the hanging ball, and just touching the cord, is released from rest and gains its velocity before striking the hanging ball. If the effect of friction is negligible, and the impact is perfectly elastic, compute the magnitude and direction of the velocity of the secondary ball in terms of its velocity before contact.
