Fantastic news! We've Found the answer you've been seeking!

Question:

A disk of mass M is spinning freely at 8.71 rad/s when a second identical disk, initially not spinning, is dropped onto it so that their axes coincide. In a short time the two disks are corotating.

(a)What is the angular speed of the new system (in rad/s)?

_______________rad/s

(b)If a third such disk is dropped on the first two, find the final angular speed of the system (in rad/s).

_______________rad/s
