Two disks are rotating about the same axis. Disk A has a moment of inertia of 3.4 kg-m^(2) and an angular velocity of +72 "rad"//s . Disk B is rotating with an angular velocity of -9.8 "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 -2.4 "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?
