The assembly shown in the figure below consists of a thin rod of length { = 22.2 cm and mass m = 1.20 kg with a solid sphere of diameter d = 10.0 cm and massM = 2.00 kg attached to its top. The assembly is free to pivot about a frictionless axle through the bottom of the rod. The assembly is initially vertical and at rest when itstarts to rotate clockwise.dMm(a) After the combination rotates through 90 degrees, what is its rotational kinetic energy (in J)?(b) What is the angular speed (in rad/s) of the rod and sphere?rad/s(c) What is the linear speed (in m/s) of the center of mass of the sphere?m/s (d) How does it compare with the speed had the sphere fallen freely through the same distance of 27.2 cm?
