A cylinder of mass `5kg` and radius `10cm` is moving on a horizontal surface with speed. `5m//s` and angular speed about axis through `C.M. 10rad//s`. Find the angular momentum of the cylinder about point of contact.

Explanation

To find the angular momentum of the cylinder about the point of contact, we need to consider both the translational and rotational contributions to the angular momentum.

### Step-by-Step Solution:

1. **Identify the Given Data:**
- Mass of the cylinder, \( m = 5 \, \text{kg} \)
- Radius of the cylinder, \( R = 10 \, \text{cm} = 0.1 \, \text{m} \)
- Linear speed, \( v = 5 \, \text{m/s} \)
