This braking distance calculator can calculate two of the following five sizes: braking distance & overall stopping distance, (braking) time, starting velocity, final velocity and acceleration / deceleration. It is primarily affected by the original speed of the vehicle and the coefficient of friction between the tires and the road surface, and negligibly by the tires' rolling resistance and vehicle's air drag. BRAKING DISTANCES. The distance it takes a vehicle to stop takes into account both the reaction time of the driver (this affects the thinking distance) and also the braking … 56.2m, and is measured on dry pavement.

This video introduces the concept of stopping distances. At 20mph, the braking distance is exactly the same as the thinking distance. Formula: d = (s * r) / 3.6. d = reaction distance in metres (to be calculated). The SI unit for stopping distance is meters. Loading... Save for later. Students. d = - 20 m/s 2. f. Which of these distances (the thinking distance and the braking distance) A car of mass 800kg is travelling along a level road at 28ms^-1. 3.6 = fixed figure for converting km/h to m/s. With the brakes applied, the car slows down. Info. Thus acceleration means the rate at which an object speeds up, deceleration means the rate at which an object slows down. In order to get a feel for this formula, we ask the following question. Video Tutorials and Resources.
