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 motion of the wheel
When a car is moving forward, the wheels are also rotating. The point of contact of the wheel with the ground is momentarily at rest, while the topmost point of the wheel is moving forward with the car's velocity plus the additional velocity due to the wheel's rotation.

### Step 2: Determine the velocity of the wheel's center
The velocity of the center of the wheel (which is also the velocity of the car) is given as 20 m/s.
