1. The figure shows tow disks, A and B, commented together, that are rotating with angular acceleration, α. The radius of the small disk B is 2/3 the radius of the larger disk. Compute the h ratio of the tangential velocity of a point on the rim of disk A to the tangential velocity of a point on the rim of disk B.

2. Also, if the two disks have an angular velocity of ω, compute the ratio of the kinetic energy of disk A to kinetic energy of disk B. Suppose that each disk has a mass M.
