What is the velocity of the highest point of a rotating wheel of a car moving with a velocity of 20 m/s ?

Explanation

To find the velocity of the highest point of a rotating wheel of a car moving with a velocity of 20 m/s, we can follow these steps:

### Step 1: Understand the Condition of Pure Rolling
In pure rolling motion, the point of contact between the wheel and the ground has zero velocity relative to the ground. This means that the linear velocity of the center of mass (VCM) of the wheel is equal to the product of the radius (R) of the wheel and its angular velocity (ω).

### Step 2: Write the Relationship for Pure Rolling
The relationship for pure rolling can be expressed as:
\[ V_{CM} = R \cdot \omega \]
