WebDerivation Energy equation. The theoretical braking distance can be found by determining the work required to dissipate the vehicle's kinetic energy.. The kinetic energy E is given by the formula: =, where m is the vehicle's mass and v is the speed at the start of braking.. The work W done by braking is given by: =, where μ is the coefficient of friction between the … WebThe size of the safe braking zone is NOT the time it takes to stop. In fact actually stopping takes around twice as long. However if you look (for example) 3.8 seconds ahead at 60mph you are looking at precisely the point where you will stop if you suddenly decide to brake. Download our braking physics spreadsheet.
