Transcribed Image Text:
The object shown in the figure below consists of a thin rod of length = 22.5 cm and mass m = 1.20 kg with a solid ball of diameter d = 10.0 cm and mass M = 2.00 kg attached to its top. The object is free to pivot about a frictionless axle through the bottom of the rod. The object is initially vertical and at rest when it starts to rotate clockwise. M (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 ball? rad/s (c) What is the linear speed (in m/s) of the center of mass of the ball? m/s (d) How does it compare with the speed had the ball fallen freely through the same distance of 27.5 cm? (Express your answer as a percentage of Vfall) swing is greater than Ⓒ Vfall by The object shown in the figure below consists of a thin rod of length = 22.5 cm and mass m = 1.20 kg with a solid ball of diameter d = 10.0 cm and mass M = 2.00 kg attached to its top.
