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