Question

the graph above describes the motion of a cyclist. the graph illustrates that the acceleration of the cyclist increases. is zero. is constant. decreases.

Explanation:

Step1: Recall acceleration - velocity - time relation

Acceleration $a=\frac{\Delta v}{\Delta t}$, which is the slope of the velocity - time graph.

Step2: Analyze the given graph

The velocity - time graph is a straight line. For a straight - line velocity - time graph, the slope is constant. Since acceleration is the slope of the velocity - time graph, the acceleration is constant.

Answer:

is constant.
