2 balls collide head-on in an elastic collision. One ball has a mass of 4.0 kg and an initial velocity of 6.5 m/s. The second ball has a mass of 2.0 kg and its initial velocity is unknown. AFTER the collision the heavier ball has a velocity of 2.5 m/s. What is the velocity of the lighter ball before and after the collision?
