A circular disc of mass 100 g and radius 10 cm' is making 2 rps about an axis passing through its centre and perpendicular to its plane. Calculate its kinetic energy.

Explanation

To solve the problem of finding the kinetic energy of a circular disc, we can follow these steps:

### Step 1: Identify the given values
- Mass of the disc (m) = 100 g = 0.1 kg (since 1 g = 0.001 kg)
- Radius of the disc (r) = 10 cm = 0.1 m (since 1 cm = 0.01 m)
- Revolutions per second (rps) = 2 rps

### Step 2: Calculate the moment of inertia (I) of the disc
