I had a conceptual question. Say I have a ball and I throw it against the wall and it bounces back. I have initial values for its velocity but not for the final velocity using the [tex]\vec{P}=m\vec{v}[/tex] I noticed that momentum is not conserved. Well if momentum is not conserved then that means it is not inelastic or elastic and the only option left is completely inelastic but..the wall can't move with the ball...whats going on? Is it just that you can't determine these kinds of collisions? Or do I have some misunderstandings of the whole concept of the elastic or inelastic collisions?
