Um, you *want* bounce.
Old ball comes from left: momentum mv. Hits and sticks, so new v <- 0.
Momentum transferred: mv.
New ball comes from left: momentum mv. Hits and bounces with perfect
elasticity, so now it's going just as fast the other direction,
so new v < -old v (negative because it's going in the other
Momentum transferred: 2mv.
