A car is moving at 20 m/s. The driver applies the brakes and the car decelerates at 1 m/s2. How long will it take the car to stop and how far will it travel until it stops

oh thats easy. you have to use ì. 20m/s = Velocity...a= Äv(velocity) over Ät(time) so it would be 20m/s divided by 1m/s and you get 20m/s squared and so on...hope it helps!
