During rolling without slipping, what is the velocity of the point in contact with the surface.

Explanation

To solve the problem of finding the velocity of the point in contact with the surface during rolling without slipping, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Concept of Rolling Without Slipping**:
- When an object rolls without slipping, the point of contact between the object and the surface does not slide. This means that the velocity of this point is zero relative to the surface.

2. **Define the Variables**:
