The acceleration of the cyclist is constant and zero
The acceleration of the cyclist is constant and zero

The acceleration of cyclist is going down
The acceleration of cyclist is going down

The acceleration of the cyclist is going up
The acceleration of the cyclist is going up

The acceleration of the cyclist is constant and non-zero

Answer 3

To determine the cyclist's acceleration, we need to observe the gradient (slope) of the velocity graph.

If the velocity-time graph is a straight line with a constant gradient, the acceleration is constant.

If the velocity-time graph is a straight line with a positive gradient, the acceleration is constant and positive.

If the velocity-time graph is a straight line with a negative gradient, the acceleration is constant and negative.

If the velocity-time graph is a curved line, the acceleration is changing.

Without the graph, it is not possible to accurately determine the cyclist's acceleration. Please provide the graph for a more accurate analysis.
