A 7. 0 kg bowling ball traveling at 2. 0 m/s collides with a stationary 0. 5 kg beach ball in an elastic collision. The bowling ball leaves the collision with a velocity of 1. 5 m/s traveling in the same direction as the beach ball. Calculate the speed of the beach ball

Answer:

7.0 m/s

This is conservation of momentum, where the momentum of the bowling ball is conserved into both the bowling ball and the beach ball.

(7.0)(2.0) = (7.0)(1.5) + (0.5)x

0.5x = 3.5

x = 7m/s
