A 100 g ball moving to the right at 4.1 m/s catches up and collides with a 450 g ball that is moving to the right at 1.0 m/s.
A. If the collision is perfectly elastic, what is the speed of the 100 g ball after the collision?
B. If the collision is perfectly elastic, what is the speed of the 450 g ball after the collision?
Express your answer to two significant figures and include the appropriate units.
I have been looking for the answer for a long time, I've had a lot of people get it wrong. Please.
