A trebuchet is a siege engine designed to hurl projectiles long distances against castle walls. One of these was built for Warwick Castle in England to demonstrate what one could do. The long end holds a projectile weighing 150 kg at a distance of 17 meters away from an axle. The other end, 1 meter away from the axle on the other end, holds a 5443 kg counterweight. Assuming the beam holding both the projectile on one end and the counterweight on the other is essentially massless compared to the other weights.

A) What are the 2 torques caused by the projectile and the counterweight? 

B) What is the moment of inertia of the system? 

C) What is the resulting angular acceleration of the projectile
