How does n=0 satisfy:

[itex]v_{f1}^2 + nv_{f2}^2 = v_{f1}^2 + v_{f2}^2[/itex]?

If n is very small it does not begin to satisfy the relationship. I think n=1 is the only solution.

By the way, billiards players know that the angle between the cue ball and object ball is 90° (absent spin on the cue ball).

that's not the equation I got. My solution looks like

[itex]v_{f1}^2 + nv_{f2}^2 = v_{f1}^2 + n^2v_{f2}^2[/itex]
