A 45.0 kg cube is resting 0.750 m from the center of a solid 125 kg disk that is rotating at 2.80 rad/s. The radius of the disk is 2.00 m. The cube slides radially to a location 1.60 m from the center of the disk, changing the moment of Inertiaof the system. What is the new angular velocity of the system? Treat the cube as a point mass in your calculation.
