Question

There are 3 balls on a horizontal, smooth surface. A 5 kg ball comes from the left with a speedof 4 m/s. It has an elastic collision with an 8

kg ball which is at rest. The 8 kg ball then has anelastic collision with an 11 kg ball which is at rest. A. Calculate the velocity of the 5 kg ball after it collides with the 8 kg ball. Give your answer inm/s. B. Calculate the velocity of the 8 kg ball after the 5 kg ball collides with it. Give your answer inm/s. C. Calculate the velocity of the 8 kg ball after it collides with the 11 kg ball. Give your answer in m/s. D. Calculate the velocity of the 11 kg ball after the 8 kg ball collides with it. Give your answer in m/s.
