To stop a car, first you require a certain reaction time to begin braking; then the car slows under the constant braking deceleration. Suppose that the total distance moved by your car during these two phases is 57.5 m when its initial speed is 77.8 km/h, and 26.8 m when its initial speed is 50.9 km/h. What is your reaction time?
