Answer:
Average acceleration of the car is 1.167 m/s^2
Step-by-step explanation:
The speed of car with which it is travelling is 12 m/s
As the driver accelerates the car, the speed reaches 26 m/s
The change in speed in 12 seconds is
26 -12 = 14 m/s
Average acceleration is change in speed divided by time
m/s^2
