Question

A 120 gg ball moving to the right at 4.2 m/sm/s catches up and collides with a 450 gg ball that is moving to the right at 1.2 m/sm/s

Part A: If the collision is perfectly elastic, what is the speed of the 120 gg ball after the collision?

Express your answer to two significant figures and include the appropriate units.

Part B : If the collision is perfectly elastic, what is the direction of motion of the 120 gg ball after the collision?
