Explanation:
The acceleration is defined as change in velocity over a period of time interval. Mathematically it can be written as,
acceleration = change in velocity / time
acceleration = 16- 4 (meters/second) / 4 seconds
acceleration = 12 meters/second / 4 seconds
acceleration = 3 meter / second square.
So the answer shows that the car accelerates 3 meter / second square.
