A surprising find looking for something else:
http://www.physics.usyd.edu.au/~cross/

Somewhat extensive notes on various small-ball sports physics - including material on collision physics and a neat vid of a falling slinky.

I've mined:
Ball bounce for comparative data for experiments involving a ball-bearing hitting a force transducer plate.
The paper has F-t graphs for several different situations appropriate to a class and useful for answering those questions about the "force of an impact".

Including a whole section on what happens when you drop heavy objects onto Silly Putty :D
