A disk starts at rest when a force P is applied to the rope wrapped around the hub. The disk and hub together have a mass of m=5 kg and mass moment of inertia (about the center) I=2 kgm^2. The disk radius is 3 m and the hub radius is 1 m. The disk rolls without slip. If after 1 revolution, the angular velocity of the disk and hub is w=10 rad/s, Find the force P.
