There was a thread some time ago discussing the coefficient of restitution
of a ball.
In that thread it was suggested that we conduct an experiment. This I
did recording the event with a digital camera running in video mode.
This video was split into individual frames, and finally today I have created
a single frame showing the motion of the ball in every other frame (the frame
rate was 15 frames/second). This such as it is is shown in the attachment.
