What is the average velocity of the sprinter whose velocity time graph is as shown above

Answer Details

The average velocity of the sprinter can be calculated by finding the slope of the line on the velocity-time graph. Since velocity is on the y-axis and time is on the x-axis, we need to find the change in velocity (y-axis) divided by the change in time (x-axis) over a certain interval. Looking at the graph, we can see that the sprinter's velocity changes from 0 m/s to 17 m/s over a time of 2 seconds. Therefore, the average velocity of the sprinter during this time interval would be: average velocity = change in velocity / change in time average velocity = (17 m/s - 0 m/s) / 2 s average velocity = 8.5 m/s So the correct option is: 8.5ms-1.
