2 Rip cord A rip cord is a cord that is wrapped around an object; when you pull the rip cord it spins the object. F A rip cord is wrapped around a shaft of radius r and moment of inertia I. The shaft is initially at rest. If the cord is pulled with a constant force F through a distance Ar, what will the final angular velocity, w, of the shaft be? 1. Solve for w using angular kinematics. 2. Solve for w using work and energy. (You should get the same answer.)
