Show answer No Attempt 50% Part (b) Now consider a disk of mass 8 kg with radius 0.55 m. Disk rotates around itself once every 0.35 sec. What is the rotational energy of this disk?

Explanation:

Given:

mass of disk,

radius of the disk,

time taken by the disk to complete on rotation,

We know that rotational kinetic energy is given as:

............................(1)

Now the angular speed of the disk:

The moment of inertia of a disk is given as:

Now using eq. (1):
