A 1450 kg disc with radius 3.0 m is rotating at 1500 rev/min when an 925 m·N braking torque is applied to the wheel. How long does it take for the disk to come to rest?

Step 1

Mass of the disc= 1450kg

Radius=3m

Angular velocity=1500rev/min

Step 2

Moment of inertia of the circular disc about its center.

Step 3

As we know, that braking torque will produce deceleratio...
