Two disks are rotating about the same axis. Disk A has a moment of inertia of 3.6 kg· m2 and an angular velocity of +7.6 rad/s. Disk B is rotating with an angular velocity of -10.8 rad/s. The two disks are then linked together without the aid of any external torques, therefore that they rotate as a single unit with an angular velocity of -2.6 rad/s. The axis of rotation for this unit is the same as that for the separate disks. What is the moment of inertia of disk B?
