Question

A car accelerates from 4 meters/second to 16 meters/second in 4 seconds. The car's acceleration is

Answer 1

Answer:

3 meter / second square.

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.
