[/URL]Homework Equations
Conservation of momentum
Conservation of kinetic energy
The Attempt at a Solution
I really have no idea. I don't know the velocity of A before the collision and i don't know the speed of A after the collision. So i can't use the conservation of momentum. I also know its not an elastic collision because I am told "the restitution is e=0.5". Should i have been told some kind of equation to allow me to work this out or am i missing something?
