The next project that I am doing with my 13 year old daughter is to build a catapult.
The experiment is to find the angle of release that lets the projectile travel furthest. Also it is an exercise where I can teach her to use hand tools to build the machine.
The idea is to construct it so the 'firing' arm will begin in the horizontal position and travel through 90 degrees to the vertical, hit a stop and release the projectile. With it mounted on a timber base we can lift one end to alter the elevation in say 5 degree increments to carry out the experiment.
My question to you all is can the answer be found by maths calculation and if so how?
