A ball has a mass of 0.25 kg and is moving to the right at 1.0 m/s. It hits a ball of mass 0.15 kg that is initially at rest. After the collision, the 0.15 kg ball moves off to the right with a velocity of 0.75 m/s.
What is the final velocity of the 0.25 kg ball?
0.42 m/s to the right
0.42 m/s to the left
0.55 m/s to the right
0.55 m/s to the left
