Stopping Distance
Total stopping distance — reaction + braking
Formula: total_distance = speed × reaction_time + speed² ÷ (2μg)
Total distance a vehicle takes to stop from a given speed, including reaction time + braking distance. Use to calibrate safe following distances. Friction varies with road surface (wet/dry/icy).
