    Answer: 3 m/s^2

    Explanation:

    Average acceleration of car = ?

    Initial velocity = 0 m/s

    Final velocity = 15 m/s

    Time taken = 5 seconds

    Recall that acceleration is the rate of change of velocity per unit time

    i. e Acceleration = (Final velocity - Initial velocity) / Time

    Acceleration = (15m/s - 0m/s) / 5seconds

    = 15m/s / 5 sec

    = 3 m/s^2

    Thus, the average acceleration of the car is 3 m/s^2
