Rolling and bouncing ball

Hi…

I followed this tutorial to make a bouncing ball in flash. Its AS2 so it took me some time to make it work in AS3:P Now i want to make the ball roll down a slope, fall and bounce when it hits the ground. Anybody know a way to do this?? Any tutorials?? I have attached my .fla if you want a look at it.:smiley:

Thanks:D
