A disk of mass m is spinning freely at 6.00 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? (b) If a

third such disk is dropped on the first two, find the final angular

speed of the system.

Step 1

**Given:**

Mass of the disc = m

Angular velocity = 6 rad/s

Step 2

Calculating the new angular velocity if another dis...
