How do I build a catapult that launches a tennis ball 100 ft?
For my physics class, we are supposed to build a catapult to launch a tennis ball a tennis ball as far as possible. We can not use any slingshot designs. Can you point me in the direction of what type I should build? Thanks.
lots of springs
