After the collision, is it correct that mass 1 moves in positive x direction but mass 2 rebounds and moves in negative x direction? If so, is this the equation for momentum:

m[itex]_{2}[/itex]v[itex]_{2i}[/itex]=m[itex]_{1}[/itex]v[itex]_{1f}[/itex]-m[itex]_{2}[/itex]v[itex]_{2f}[/itex]

And the equation for KE:

[itex]_{2}[/itex](v[itex]_{2i}[/itex])^2=m[itex]_{1}[/itex](v[itex]_{1f}[/itex])^2+m[itex]_{2}[/itex](v[itex]_{2f}[/itex])^2

And if solving for v[itex]_{1f}[/itex] :

v[itex]_{1f}[/itex]=[itex]\sqrt{\frac{m_{2}(v_{2i})^2}{m_{1}}}[/itex]

And the velocity of this mass should be in the positive x direction.

Does everything look correct?
