HS: Physics Olympics- Catapult Print

Mr. Jeffrey Richard's Physics classroom is gearing up for the State Physics Olympics which will be held on March 17th at UNI in Cedar Falls. One category that is interesting is the SELF PROPELLED CATAPULT. The catapult must carry and launch a ping-pong ball. It must not exceed certain size dimensions and the energy sources shall consist of any elastic storage device (rubber bands, bungee cords, leaf springs, etc). No other mechanical or chemical device may provide energy to either the movement of the apparatus or the propulsion of the ping-pong ball. Pictured are Sander V & Spencer W; builders of this catapult that will compete in the State Physics Olympics. Good Luck!
