Problem

A pool table is $4$ feet wide and $8$ feet long, and is
arranged in a coordinate system where $1$ unit is $1$ foot so that
one corner is at $(0,0)$ and the $8$-foot side lies along the
$x$-axis. If you strike a ball initially placed at $(2,2)$ so
that its first bounce is against the wall at $y = 4$, in how many
places can you hit that wall so that the ball goes into the pocket
at $(8,0)$ after exactly $11$ total bounces against the walls
$y=0$ and $y=4$? It doesn't matter how many times the ball
bounces against the walls at $x=0$ and $x=8$. Assume the ball
always bounces so that it's angle of incidence is equal to it's
angle of reflection.
