Catapult Project Madison taylor, jordan rose, blake guy

Our challenge is to design and produce a working catapult. within specified guidelines, that is adjustable and propels hollow plastic practice golf balls (weighing about 14.5 grams each) at a scoring target between 15’ and 25’ away. Document the math and science used to complete and improve accuracy. The guidelines we have to follow is that it must fit in a box that is 2 feet wide and 1.5 feet high. The catapult must be made entirely from PVC pipe, with the exception of the launch mechanism and firing mechanism.

Supplies/Materials: PVC Piping (3’2’’), 90 degree connectors (5), T-connectors (5), Rubber band (1’/24’’), Bungee (1’/24’’), 2 small PVC “rods” (2’), 2 larger PVC “rods” (2’), 2 vertical PVC “rods” (1.5’), 1 horizontal PVC “rod” (2’), and 1 long PVC “rod” (1.7’). Out of pocket expenses: T-connectors.

This was a picture we found on the web for our inspiration.
