Ball falling of cliff (Squash and Stretch principle)

Here I have now made a more realistic situation for the bouncy ball instead of it just bouncing forever. Now it rolls of a ledge onto a hard surface, i started by drawing a diagram to get an idea of how the ball would react.

After that i created the animation using Paint.Net and Movie Maker. Each frame is 0.04 seconds long which is 25 frames per second.
