A moving shuffleboard puck has a glancing collision with a stationary puck of the same mass. If friction is negligible, what are the speeds of the pucks after the collision?

3. The attempt at a solution

I ended up with this:

0.95 = Vx1*cos50 + Vx2*cos40

and

0= Vy1*sin50 - Vy2*sin40

I know that both momentum and energy are conserved in elastic collision but I got no idea how to actually apply the concept. I think i'm looking too much into it and missing something simple. Thanks
