A car is traveling at 15m/s. How far will the car travel beforecoming to a complete stop, being the car decelerates at a rate of5m/s^2?

I know that it will take the car 3 seconds to come to a completestop, but I do not know what equation to implement in order toconfigure the distance the car will travel in meters.
