Considering that while traveling on a road with a final speed of 15 m/s, and an initial speed of 24 m/s, with a given time of 12 seconds.

To calculate the acceleration, we apply the following formula:

α = Vf - Vo/t

We add our data into the formula and solve:

α = 15 m/s - 24 m/s/12 sec

α = -0.75 m/s²

Therefore, the acceleration of the car is -0.75 m/s².
