Answer:
A. 5 m/s
Explanation:
From the graph, for the first 2 seconds, the graph is a straight line meaning that the slope is a constant.
Average speed of an object is the rate of change of position. Here, the position of the object changes from 0 m to 10 m for a time interval of 2 seconds.
The change in position () and time interval (
) are given as:
Therefore, the average speed () is given as the ratio of the total change in position and the time interval for the change.
Hence, the average speed is 5 m/s.
