To accurately describe the cyclist's acceleration based on the graph of their velocity over time, we need to analyze how the velocity changes.
- If the velocity is increasing at a constant rate, the acceleration is constant and non-zero.
- If the velocity is decreasing at a constant rate, the acceleration is constant and non-zero, but negative.
- If the velocity is constant (horizontal line), the acceleration is constant and zero.
- If the velocity is fluctuating up and down, the acceleration is not constant.
As I do not have the graph to analyze directly, please refer to these descriptions:
- If the graph shows a line inclined upwards, select "The acceleration of the cyclist is constant and non-zero."
- If the graph shows a line inclined downwards, select "The acceleration of the cyclist is going down."
- If the line is horizontal, select "The acceleration of the cyclist is constant and zero."
Using this information, choose the response that best describes the graph you have.
