Hi all.
I am learning physics and I have the following problem.
Suppose there is a ball of mass m traveling with velocity v towards a wall at rest.
The ball bounces back and it's now at velocity -v.
Since the wall is always at rest, it follows that the total momentum before the collision was mv, but after the collision it is -mv, so how is the momentum conserved?
It is clear that I am doing something wrong or missing something simple, but I can't spot what.
Any help
