Ball B is hanging from a cord of negligible weight. An identical ball A is measured 3m above the hanging ball and just touching the cord, is released from rest and acquires a velocity (V_o) before striking ball B. Assuming perfectly elastic impact and no friction, compute the A) magnitude of the velocity of ball A in terms of V_o or velocity before impact B.) direction of the velocity of ball A in terms of V_o or velocity before impact (note: should be in angle with respect to north, east, west, south)
