A 30 kg kid is riding on the front of a 60 kg shopping cart that is rolling (in the positive direction) at 3.8 m/s. The kid jumps off the cart by pushing off it as it rolls. The kid continues forward at 8.4 m/s. What is the final velocity of the shopping cart afterwards?
Homework Answers
Concept - use momentum conservation principle
to find the final velocity of the shopping cart after the kid jumps
off.
