Can someone please help me on how to solve this problem?(adsbygoogle = window.adsbygoogle || []).push({});

Two disks, A and B, are cemented together rotating with angular velocity. The radius of the small disk B is 2/3 the radius of the larger disk A.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, calculate the ratio of the kinetic energy of disk A to the kinetic energy of disk B. Assume that each disk has a massw.M
