A purple ball that has a mass of 4.2 kg and an orange ball with a mass of 4.7 kg collide in an elastic collision. The purple ball is initially moving to the left
with a velocity of 15 m/s. The orange ball is moving to the right with a velocity of 12 m/s. If the final velocity of the orange ball is 11.3 m/s, what is the final
velocity of the purple ball?
