A boy is standing on a canoe. The boy decides to jump off the canoe and go to the dock nearby. The boy has a mass of 60.0 kg, and the canoe is 180.0 kg. The boy jumps off the canoe with 4.0 m/s [W] velocity. Any friction in water can be ignored for this question.

a) What is the momentum of the boy as he jumps off?

b) What is the momentum of the canoe as the boy jumps off?

c) What is the final speed of the canoe just after the boy jumps off?

A child throws a snowball at a tree and it sticks to the tree. Does this motion defy the Law of Conservation of Momentum? Explain.
