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.
