Question

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

Which of the following describes the intercepts on the graph? (1 point)


The initial acceleration of the runner was 8 m/s2, and the runner stopped after 6 seconds.

The initial acceleration of the runner was 6 m/s2, and the runner stopped after 8 seconds.

The initial velocity of the runner was 8 m/s, and the runner stopped after 6 seconds.

The initial velocity of the runner was 6 m/s, and the runner stopped after 8 seconds.

Answer 1

The last answer...
At time 0, the velocity is 6.
When the velocity is 0, the time is 8

Answer 2

The initial velocity of the runner was 6 m/s, and the runner stopped after 8 seconds.

Explanation:

We are given a graph that shows the velocity f(t) of a runner during a certain time interval.

From the graph it can be seen that , at time 0, the velocity of the runner = 6m/s.

Hence, the initial velocity of the runner = 6 m/s

Also, the graph stops after time = 8 seconds.

It implies the runner stopped after 8 seconds.

Hence, the statement which describes the intercepts on the graph is :

"The initial velocity of the runner was 6 m/s, and the runner stopped after 8 seconds."
