Calculate the angular speed of the hour hand of a clock .

Explanation

To calculate the angular speed of the hour hand of a clock, we can follow these steps:

### Step 1: Understand the Angular Displacement
The hour hand of a clock completes a full rotation (360 degrees) in 12 hours. In terms of radians, this full rotation is represented as:
\[ \text{Total Angular Displacement} = 2\pi \text{ radians} \]
