Answer:

A. 5 m/s

Step-by-step 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 (
\Delta x) and time interval (
\Delta t) are given as:


\Delta x=10-0=10\ m\\\Delta t=2-0=2\ s

Therefore, the average speed (
s_(avg)) is given as the ratio of the total change in position and the time interval for the change.


s_(avg)=(\Delta x)/(\Delta t)=(10-0)/(2-0)=(10)/(2)=5\ m/s

Hence, the average speed is 5 m/s.
