Two Disks Are Mounted on Low-Friction Bearings on a Common $\omega$

question 2

Multiple Choice

Two disks are mounted on low-friction bearings on a common shaft. The first disc has rotational inertia I and is spinning with angular velocity $\omega$ . The second disc has rotational inertia 2I and is spinning in the same direction as the first disc with angular velocity 2 $\omega$ as shown. The two disks are slowly forced toward each other along the shaft until they couple and have a final common angular velocity of:

• A) 5 \( \omega \)/3
• D) \( \omega \)
• E) 3 \( \omega \)
