The car's acceleration is 10 m/![s^{2}](/tpl/images/0838/7900/c60b2.png)
Explanation:
The "acceleration" tells you how the velocity's rate changes over a specific period of time.
The formula is: a (acceleration) =![\frac{change in velocity}{change in time}](/tpl/images/0838/7900/a05e4.png)
The velocity changed from 0 m/s to 20 m/s while time changed from 0 sec. to 5 sec.
Therefore: a =
= 10 m/
(this refers to the rate at which the car's velocity changed over time)
