A crash stop maneuver (from 'full ahead' to 'full reverse') can stop a fully loaded supertanker within approximately three kilometres, which takes about 14 minutes.
The turning diameter is almost two kilometres.
(These values vary according to ship size and weight, of course).
Yes, friction affects stopping distance. The greater the friction the lower the stopping distance; the lower the friction the greater the stopping distance.
Stopping distance at 30mph = 23m
Stopping Distance = 15 feet
Stopping Sight Distance
Stopping Distance = about 146.25 feet.
The steeper the slope, the longer the stopping distance is.
The stopping distance of a car increases.
Trains require a long stopping distance.
Stopping distance also increases.
Stopping distance at 40mph = 36m
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.
Stopping Distance = about 315 feet at 70 mph
