The change in velocity of a car that starts at rest and has a final velocity of 20 meters/second north would be 20 meters/second.
The rate of change of the velocity with respect to time is known as the acceleration of the object. Generally, the unit of acceleration is considered as meter/seconds².
As given in the problem we have to find the change in velocity of a car that starts at rest and has a final velocity of 20m/s north,
the final velocity of the car = 20 meters/second north
Change in the velocity = final velocity - initial velocity
=20 - 0
= 20 meter/second
Thus, the change in the velocity would be 20 meters/second
