Bouncing Ball on Slope Physics?

[Kaitenshin]

Does anyone know where I can find a tutorial (or get some code!) on flash physics concerning dropping a ball in motion onto a slope, or any surface for that matter.

Heres a sloppy paint drawing I put together to describe what I mean. The ball would have a velocity and the would bounce off the slope according to its angle or structure.

Any help would be amazing. Thanks guys.
