Suppose a car is traveling at +22.3 m/s, and the driver sees a traffic light turn red. After 0.351 s has elapsed (the reaction time), the driver applies the brakes, and the car decelerates at 8.00 m/s2. What is the stopping distance of the car, as measured from the point where the driver first notices the red light?
22.3*.351 + braking
but braking can be found from
vf^2=vi^2+2ad solve for d. vf=0, a given, vi=22.3
add the distances.
