Calculate the kinetic energy of rolling ring of mass 0.2 kg about an axis passing through its centre of mass and perpendicular to it, if centre of mass is moving with a velocity of 3 m/s.

Explanation

To calculate the kinetic energy of a rolling ring, we will follow these steps:

### Step 1: Understand the given data
- Mass of the ring (m) = 0.2 kg
- Velocity of the center of mass (v) = 3 m/s

### Step 2: Identify the formula for kinetic energy of a rolling object
The total kinetic energy (KE) of a rolling object can be expressed as:
...
