The tangential force F shown in figure below is applied to a disc is allowed to rotate about an axis through its center. The diameter of the disc is 24.0 cm. The magnitude of this tangential force is given in the graph of F vs. Angular Position. With the disc at rest initially and ignoring frictional torque, the disc's angular velocity after one full rotation is -31.4 rad/sec. What is the moment of inertia of the disk?
