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
