A disk has a moment of inertia of 2.50 x 10°2 kg-m² and spins on a frictionless axis through its center at an initial angular speed of 22.2 rad/s. A ring, initially not rotating, of mass 0.250 kg and radius 0.200 m, is dropped vertically onto the disk and sticks so that the combination rotates about a common axis, through their centers. What is the new angular speed of the system? Note: I¡ing: MR². %3D
