A ball of mass 0.240 kg that is moving with a speed of 5.9 m/sm/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 3.2 m/s. (1)Calculate the velocity of the target ball after the collision. Express your answer to two significant figures and include the appropriate units. (2)Calculate the mass of the target ball. Express your answer to two significant figures and include the appropriate units.
