Understanding the Concepts

* Acceleration: The rate of change of velocity over time.

* Average Acceleration: The total change in velocity divided by the total time taken.

Formula

Average acceleration (a) = (Final velocity (v) - Initial velocity (u)) / Time (t)

Given Information

* Initial velocity (u) = 0 m/s

* Final velocity (v) = 25 m/s

* Time (t) = 8.0 s

Calculation

a = (25 m/s - 0 m/s) / 8.0 s

a = 25 m/s / 8.0 s

a = 3.125 m/s²

Answer

The average acceleration of the car is 3.125 m/s².
