A ball of mass 0.265 kg that is moving with a speed of 5.1 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 3.3 m/s . a) Calculate the velocity of the target ball after the collision. b) Calculate the mass of the target ball.

Solve using conservation of momentum and conservation of energy.
