The assembly shown in the figure below consists of a thin rod of length f = 23.9 cm and mass m = 1.20 kg with a solid sphere of diameter d = 10.0 cm and mass M = 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 it starts to rotate clockwise. d M m i (a) After the combination rotates through 90 degrees, what is its rotational kinetic energy (in )? (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 28.9 cm?
