Bouncing ball with rotation

[Fu-Kwun Hwang]

The following simulation show a ball bouncing off the ground.
The ratio of velocity after bouncing to velocity before bouncing is eta.
i.e. vy'=eta *vy; (eta=0.95 as default)

The momentum change
Assume the friction coeffieient is mu=0.1
The friction between ball and the ground produce momentum change and angular momentum change during bouncing.
