2) A cylindrical rod of radius r = 2.00 cm and mass 1.25 kg is upright on the edge of a rotating disk of mass 10.0 kg and radius 25.0 cm as is shown in diagram (a) below. The system is rotating at 15.0 rad/s. The rod falls on its side as shown in diagram (b) Diagrams (c) and (d) present a side view. What is the new angular velocity of the system? How much work was done in changing the shape of the object? (b) Looking down Side View
