The mass of a hoop of radius 0.30 m is 2kg. It rolls along a horizontal floor so that its centre of mass has a speed of 2 m/s. What is the work done to stop it ?

Explanation

To solve the problem of finding the work done to stop a rolling hoop, we will follow these steps:

### Step 1: Identify the parameters
- Mass of the hoop (m) = 2 kg
- Radius of the hoop (R) = 0.30 m
- Speed of the center of mass (V_cm) = 2 m/s

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