I have created a gravity powered catapult for a class project and then modeled it using solidworks motion. I am able to get the catapult to move based on gravity, but when it releases its ball at the end of the cycle, the ball acts as if almost no force has been applied to it. The ball flies forward a small distance, then falls down through the catapult.
Based on the prototype we built, it should move forward several feet.
Attached is a video and the part files, any help fixing this would be appreciated.
