Homework Help: Physics

Posted by Rachel on Monday, November 9, 2009 at 10:41pm.

Please Help !

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.

The Law of Conservation of Energy states: "If there is no net force acting on a system of objects, the total momentum in that system before a collision is equal to the total momentum in the system after the collision."

How can I use this to explain how the aforementioned situation does not defy the law. Maybe help by explaining where the momentum would go given that p=mv and neither object is changing mass, but they are both coming to a rest.
