A ball of mass 0.220 kg that is moving with a speed of 6.3 m/s collides head-on and elastically with another ball initially at rest. Immediately after the collision, the incoming ball bounces backward with a speed of 3.6 m/s. (Assume the positive direction is forward.)

(a) Calculate the velocity of the target ball after the collision.
(b) Calculate the mass of the target ball.
