To determine where the instantaneous velocity is less than 0, we need to analyze the graph provided. Instantaneous velocity is negative when the slope of the position-time graph is negative.

Based on the graph you provided, here is what can be inferred:

1. The slope of the curve is positive from point A to B, meaning the instantaneous velocity is positive in this region.
2. From B to C, the slope is zero (horizontal), meaning the velocity is zero.
3. After C, the slope turns negative between C and D, indicating that the instantaneous velocity is less than 0 in this region.
4. Continuing past D, the slope remains negative through point E and further down until it becomes horizontal again at F. Hence, velocity is negative between C and F.

Thus, the instantaneous velocity is less than 0 from point C to F.

Would you like further details or have additional questions?

Here are 5 related questions that might help you expand your understanding:

1. What is the difference between average velocity and instantaneous velocity?
2. How do we calculate the instantaneous velocity mathematically?
3. What physical meaning can we infer when the slope of the graph is zero?
4. What would the graph of acceleration look like based on this position-time graph?
5. How does the curvature of the graph affect the velocity and acceleration?

Tip: Remember that instantaneous velocity is directly related to the slope of a position vs. time graph. When the slope is negative, the velocity is negative!
