The ball is accelerating
Explanation:
On a distance-time graph, the slope of the graph represents the speed of the object represented.
Let's therefore calculate the slope (so, the speed of the ball) in the two intervals given.
In the first second, we have:
So the average speed is
In the next second, we have:
So the average speed is
We notice that the speed of the ball has increased from 20 m/s in the first second to 40 m/s in the next second: this means that the speed of the ball is increasing, and therefore, the ball is accelerating.
