Question

A car is moving with a rate of 20 m/s when the driver sees a squirrel in the road and hits the
breaks. The car comes to a stop (o m/s), 4 seconds later and the squirrel is saved! :-)
What is the FINAL velocity of the car?

Answer 1

The finally velocity is 0, the car comes to a complete stop so it’s velocity changes from 20 m/s to 0m/s (motionless)
