A 180-g billiard ball is shot toward an identical ball at velocity vi = 7.60 m/s. The identical ball is initially at rest. After the balls hit, one of them travels with velocity v1, f = (1.80 + 2.28) m/s. What is the velocity of the second ball after the impact? Ignore effects of friction during this process. (Express your answer in vector form.) V2f=______ m/s
