A ball is hanging from a card of negligible weight. A secondary ball with the same weight as the first ball is measured 3m 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.
