Question

1. the graph above represents the motion of a cyclist. the graph shows that the cyclist was always — moving in the same direction moving at the same rate increasing in speed changing direction and slowing down clear all acceleration - time graph acceleration (m/s²) 4 3 2 1 0 0 1 2 3 4 5 time (s)

Explanation:

Step1: Analyze acceleration - time graph

The acceleration values are all positive ($a> 0$) on the given graph for the time - interval shown.

Step2: Recall the relationship between acceleration and speed

When acceleration $a>0$, the speed of an object is increasing (assuming the initial velocity is non - negative or the positive acceleration overcomes any initial negative velocity effect). Since the acceleration is always positive for the cyclist in the given time interval, the cyclist is always increasing in speed.

Answer:

C. increasing in speed
