Homework Help: Physics

Posted by Jon on Monday, November 9, 2009 at 10:40am.

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.

I'm thinking yes.
Given that p(momentum)= mass x velocity, even though the tree is stationary, it would have a much greater momentum due to it's mass than the nearly weightless snowball even though it is in motion. Because the tree has greater momentum than the snowball, the snowball would not be able to change the motion of the tree (rest).

Am i correct? Is there a better way to explain this? Any suggestions?
Thanks
