Question

The graph below shows the velocity f(t) of a runner during a certain time interval:

Velocity (m/s)
Time (s)
Which of the following describes the intercepts on the graph? (1 point)
The initial velocity of the runner was 8 m/s, and the runner stopped after 2 seconds.
O The initial velocity of the runner was 2 m/s, and the runner stopped after 8 seconds.
O The initial acceleration of the runner was 8 m/s², and the runner stopped after 2 seconds.
The initial acceleration of the runner was 2 m/s2, and the runner stopped after 8 seconds.

Answer 1

The correct option that describes the velocity time graph is:

Option B: The initial velocity of the runner was 2 m/s, and the runner stopped after 8 seconds.

How to Interpret the Velocity Time Graph?

The velocity time graph is a graph that shows the relationship between time on the x-axis and velocity on the y-axis.

Now, from the velocity time graph attached, we see that:

The velocity when time is 0 is: v = 2 m/s

He kept running for a total of 8 seconds and as such the correct option that describes the velocity time graph is:

Option B: The initial velocity of the runner was 2 m/s, and the runner stopped after 8 seconds.
