Acar accelerates from 4 meters/second to 16 meters/second in 4 seconds. the car’s acceleration is meters/second2.

3 metters per second square

Explanation:

The car goes from 4m/s to 16 m/s in 4 seconds, then the slope of the velocity (Or the mean aceleration) can be calculated as:

A = (16 m/s - 4 m/s)/(4s - 0s ) = 12m/s/4s = 3m/s^2

So the average acceleration in these 4 seconds ins 3 metters per second square
