Question

the average acceleration is the ratio of which of the following quantities?
question 5
the following questions refer to the following velocity - time graph of a jogger. the positive direct
the jogger is at rest during which interval?

Explanation:

Step1: Recall acceleration formula

The formula for average acceleration $a_{avg}=\frac{\Delta v}{\Delta t}$, where $\Delta v$ is the change in velocity and $\Delta t$ is the change in time.

Answer:

The average acceleration is the ratio of $\Delta v$ to $\Delta t$, so the correct - answer among the options (assuming the third option is $\frac{\Delta v}{\Delta t}$) is $\frac{\Delta v}{\Delta t}$.
