This project by far has been my favorite and most anticipated since I heard about it

                                                                   Calculations:

Unfortunantly we calculated the energy tranfer wrong and didnt have time to fix it so we got 4.8%

The kinetic energy produced by the tribuchet was was 25 joules and the potential was 51.2 joules and when it does luanch it realeases the payload (the payload is 0.013 kgs) at a  ~60 degree angleit shot at an average range of 34 meters and it went y =19.6mv high Vx=17 m/s Vy=9.8 m/s
