Two disks are rotating about the same axis. Disk A has a moment
of inertia of 2.81 kg·m2 and an angular
velocity of +7.74 rad/s. Disk B is rotating with an angular
velocity of -7.21 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
-1.94 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?
