A 0.500 kg object at 4.00 m/s hits a 3.50 kg object at rest elastically. The small object:
ABounces backward
BStops completely
CSpeeds up forward
DSticks to the big one
Answer & Solution
Correct answer: A. Bounces backward
1. Its final velocity is -3.00 m/s.
2. It bounces backward.
3. The big object moves forward at 1.00 m/s.
