Homework Equations
No idea how to attempt this at all.
I am thinking that you use the momentum equation:
m1v1 +m2v2 = m1v1' +m2v2'
And potentially the kinetic energy equation (if it's elastic):
0.5m1v1^2 +0.5m2v2^2 = 0.5m1v1'^2 +0.5m2v2'^2
The Attempt at a Solution
I have no idea where to start. If you could help that would be great.
Thanks.
