A solid cylinder, of mass 2 kg and radius 0.1 m, rolls down an inclined plane of height 3m. Calculate its rotational energy when it reaches the foot of the plane.

Explanation

To solve the problem of calculating the rotational energy of a solid cylinder rolling down an inclined plane, we can follow these steps:

### Step 1: Calculate the Potential Energy at the Top of the Incline
The potential energy (PE) at the height \( h \) is given by the formula:
\[ PE = mgh \]
where:
