Textbook Problem

# A bowling ball onboard a space station is floating at rest relative to the station and an astronaut nudges a Ping-Pong ball toward it at speed v, initiating a perfectly elastic head-on collision. Which answer is closest to the Ping-Pong ball’s speed after the collision? (a) 0 (b) v/2 (c) v (d) 2v (e) 3v

To determine
The speed of ping pong ball after collision.

Explanation

In a perfectly elastic collision, the speeds of the objects before and after collision remain the same.

Conclusion:

The relative speed of the objects is v. As the ping pong ball collides with the stationary bowling ball, its final speed is equal to v...
