Which of the following best describes the acceleration of the cyclist? A. decreasing B. zero and constant C. constant but non-zero D. increasing

Question

The line starts at +1.0 on the y axis and just continues to go up in a straight line across the graph from then.

Answer 1

To determine the acceleration of the cyclist based on the description of the graph, we can analyze the information provided:

1. The graph starts at +1.0 on the y-axis and continues to go up in a straight line: This indicates that the velocity (y-axis) is increasing linearly with respect to time (x-axis).

2. A straight line on a velocity-time graph implies that the velocity is changing at a constant rate.

From these observations, we can conclude that the acceleration must be:

C. constant but non-zero

This is because the cyclist is accelerating at a steady rate, indicated by the linear increase in velocity over time.
