An energy of `484 J` is spent in increasing the speed of a flywheel from 60 rpm to 360 rpm. Calculate moment of inertia of flywheel.

Explanation

To find the moment of inertia of the flywheel, we can follow these steps:

### Step 1: Understand the Energy Change
The energy spent in increasing the speed of the flywheel is converted into rotational kinetic energy. The change in kinetic energy (ΔKE) is equal to the work done on the flywheel, which is given as 484 J.

### Step 2: Write the Formula for Rotational Kinetic Energy
The rotational kinetic energy (KE) of a rotating object is given by the formula:
\[
