1. The problem statement, all variables and given/known data How simple mechanics equations can be used to describe force, acceleration, speed, distance, etc. of a catapult. 2. Relevant equations This is my question. I have the time and distance travelled already, I'm hoping for some help as to what formulas to use. I don't need them filled out for me, just some suggestions as to what formulas will describe which parts 3. The attempt at a solution Not necessary, just some general formula help...I am fine with formulas and explanations based on formulas once I get them, but my formulas were all in my physics book, which I no longer have.
