Question

A 180-g billiard ball is shot toward an identical ball at velocity

v_i = 6.90 m/s.

The identical ball is initially at rest. After the balls hit, one of them travels with velocity

v_1, f = (1.80 + 2.22) 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.)

v_2, f =

m/s
