Two disks are rotating about the same axis Disk A has a moment of inertia of 4.11 kg m2 and an angular velocity of 9.06 rad s Disk B is rotating with an angular velocity of 8.24 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 2.18 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

![I_B(\omega^2-\omega_B^2)=I_A(\omega_A^2-\omega^2)\\\\I_B=\frac{I_A(\omega_A^2-\omega^2)}{\omega^2-\omega_B^2}=\frac{4.11kgm^2[(9.06\frac{rad}{s})^2-(2.18\frac{rad}{s})^2]}{(2.18\frac{rad}{s})-(8.24\frac{rad}{s})}=-4.66kgm^2](/tpl/images/0601/3415/77fea.png)
