Maximum Angle for Non-Null Initial Velocity of Billiard Ball Hit by Cue

OK, that's what I got, too.

So, in the end, the two conditions should be
$μ≥1$
$θ=45°$
So the trick with this kind of problems is to figure out which forces can be though as impulsive in that laps of time, and then you just draw the fbd and solve it. Am I forgetting about anything else?

I think that's essentially it.
