Can someone please help me on how to solve this problem? Two disks, A and B, are cemented together rotating with angular velocity a . The radius of the small disk B is 2/3 the radius of the larger disk A. a) Calculate the 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? b) If the two disks in problem a have an angular velocity of w, calculate the ratio of the kinetic energy of disk A to the kinetic energy of disk B. Assume that each disk has a mass M.
