**Problem Statement:** Two disks are rotating about the same axis. Disk A has a moment of inertia of 5.00 kg·m² and an angular velocity of +6.60 rad/s. Disk B is rotating with an angular velocity of -10.6 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 -2.80 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? **[Answer box for input]** _______ kg·m²
