i have a project to build a catapult that is at most 4.4 lbs. and whose volume is .8 meters. it has to launch a koosh ball 10 meters. any ideas on how to build a good one? what factors affect how far it throws?

Seems as if there is information missing. Spring constants are in force/unit length of displacement, such as pounds per inch for linear springs, or pounds per degree for torsional springs. Then you need to figure out displacement of the spring for each position relative to the fulcrum and the elevation angle of the throwing arm at the point of release. Force of the throwing arm = spring constant x spring displacement. The total force of the throwing arm needs to overcome the mass of the projectile x gravity x sine of the elevation angle of the throwing arm at point of release.
