A softball of mass 0.220 kg that is moving with a speed of 5.0 m/s (in the positive direction) collides head-on and elastically with another ball initially at rest. Afterward the incoming softball bounces backward with a speed of 3.4 m/s.
Calculate the velocity of the target ball after the collision.
___ m/s
Calculate the mass of the target ball.
____ kg
