When you try to stop your car in an emergency, there is some time before you can react.Your car is going 25 m/s and your reaction time is 0.20 s, then after you hit your brakes it decelerates at 9.5 m/s2. How far will your car travel before it stops?

as in your Anonymous post,
It takes t = 25/9.5 seconds to stop once the brakes are applied.
s = 25*0.2 + 25t - 4.75 t^2 is the total stopping distance
