A car is traveling at 20.0 m/s, and the driver sees a traffic light turn red. After 0.530s (reaction time), the driver applies the brakes, and the car decelerates at 7.00m/s^2. What is the stopping distance of the car, as measured from the point where the driver first sees the red light?

With the assumption that the initial pos. of the car is 0m.
