Two disks are rotating about the same axis. Disk A has a moment of inertia of 7.64 kg·m2 and an angular velocity of +7.58 rad/s. Disk B is rotating with an angular velocity of -9.17 rad/s. The two disks are then linked together without the aid of any external torques, so that they rotate as a single unit with an angular velocity of -2.69 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?
