thanks all for your help im sure ill do fine now

Im a highschool student who needs to build a catapult for my physics class, there arent any specifics to the build of the catapult(no air cannons) but it just needs to be able to launch a superball 2 meters. I was wondering if anyone could offer me some advice on a good design to use, i was thinking of a trebuchet but i think that might be to difficult to build on this fairly small scale. Like I said other then compressed air, anything goes.
