These are the old British measures which haven't changed since th 1960's.
In modern vehicles far shorter stopping distances can be obtained.

10 meters for thinking distance and 17 meters for stopping
Total stopping distance is the thinking distance (The distance it takes for your brain to process the event and decide to stop the car) and the stopping distance (The distance it takes to stop the car once deceleration has begun) added together.
Total stopping distance is the thinking distance (The distance it takes for your brain to process the event and decide to stop the car) and the stopping distance (The distance it takes to stop the car once deceleration has begun) added together.
The overall stopping distance would be around 122m (400ft) This is made up of a thinking distance of 24m (79ft) and an actual stopping distance of 98m (321ft). The thinking distance is around 3m for every 10mph of speed and the overall stopping distance is calculated as follows: 2x20 ft at 20mph 2.5x30 ft at 30mph 3x40 ft at 40mph 3.5x50 ft at 50mph 4x60 ft at 60mph 4.5x70 at 70mph 5x80 at 80mph = 400 ft james s
The distance and direction between starting and stopping positions is displacement.
The faster you are going the longer the stopping distance is. The slower you are going the shorter the stopping distance is. E.G. Speed of a car Thinking distace Breaking distance Total stopping distance mph meters meters meters 30 9 14 23 40 12 24 36 50 15 38 53 70 21 75 96
Yes, friction affects stopping distance. The greater the friction the lower the stopping distance; the lower the friction the greater the stopping distance.
The distance your vehicle travels while stopping depends on various factors such as your speed, road conditions, and reaction time. On average, a car traveling at 60 mph can take anywhere from 100-130 feet to come to a complete stop.
Stopping distance at 30mph = 23m
Stopping Distance = 15 feet
Stopping Sight Distance
Stopping Distance = about 146.25 feet.
