Is it possible that the average velocity for some interval may be zero although the average velocity for a shorter interval included in the first interval is not zero?

Explanation

To determine if it is possible for the average velocity over a certain interval to be zero while the average velocity over a shorter interval within that same interval is not zero, we can analyze the situation step by step.

### Step-by-Step Solution:

1. **Understanding Average Velocity**:
Average velocity is defined as the total displacement divided by the total time taken. Mathematically, it is given by:
\[
\text{Average Velocity} = \frac{\text{Total Displacement}}{\text{Total Time}}
