Solve for the Velocity of each mass after the collision.
Pi = Pf
Ki = Kf
The Attempt at a Solution
Okay so I've tried setting up a system of equations to solve for the unknown velocity and angles. The problem is that I can't seem to find either unknown angle. I know that momentum for each axis must be conserved and that total energy must be conserved. That gives me three equations but I can't figure out how to solve for both the velocity and the angles. I do know that θ1 + θ2 = 90°
