Hi there, can anyone help me with this problem, I'll be grateful to received your help. It was like this, we were doing an experiment on collision and this is how it goes; We place a ramp on table and a sheet of paper at the bottom of the table but close to the edge. Then we put two balls, one at the top of the ramp ready tobe release and one at the end of the ramp (stationary).Then the ball at the top of the ramp was release and hit the ball at the bottom, the diagram which I have drawn shows the direction of the two balls and a resultant.

The attempt at a solution The Question is that, we have to explain if a velocity for this experiment is conserved or not and if momentum of collision is also conserved or not?
