Two disks are rotating about the same axis. Disk A has a moment of inertia of \( 8.30 \mathrm{~kg} \cdot \mathrm{m}^{2} \) and an angular velocity of \( +4.24 \mathrm{rad} / \mathrm{s} \), Disk B is rotating with an angular velocity of \( -6.50 \mathrm{rad} / \mathrm{s} \). 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 \( -1.90 \mathrm{rad} / \mathrm{s} \). 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? Number Units
