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.
A 1.0 m/s
B 2.0 m/s
C 3.5 m/s
D 7.0 m/s
