A. Divide the change in the objects velocity by the time it takes to make that change.
Explanation:
Acceleration is a vector quantity whose magnitude is given by the following equation:
[tex]a=\frac{\Delta v}{\Delta t}[/tex]
where
[tex]\Delta v[/tex] is the change in velocity of the object
[tex]\Delta t[/tex] is the time it took to make the change in velocity
Therefore, we see that this equation corresponds to choice A.
