5. Two disks are rotating about the same axis. Disk A has a moment of inertia of 4.40 kg.m2 and an angular velocity of +6.60 rad/s. Disk B is rotating with an angular velocity of -12.0 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 -2.70 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? kg.m?
