There is a formula for the make believe world but for every day life there are way to many variables to pinpoint it. IE. What's the weather like today?, Did you have your coffee, how's the reaction time doing today? When the local mecanic told you your tires, brakes and shocks were junk do you change them
The stopping distance of a car can be determined by considering the car's speed, reaction time of the driver, and the braking distance required to come to a complete stop. The stopping distance is the sum of the reaction distance (distance traveled during the driver's reaction time) and the braking distance (distance traveled while the brakes are applied). It can be calculated using the formula: Stopping distance Reaction distance Braking distance.
Hi there! Assuming that the deceleration (or negative acceleration, if you will) is constant and the same in both cases, you can use a special kinematic formula to solve the problem. The formula follows: (final velocity)^2 = (initial velocity)^2 + [ 2 * (deceleration) * (braking distance) ] Rearranged to our needs the formula reads: braking distance = [1/2] * -(initial velocity)^2 / (deceleration) * this equation assumes that the final velocity is zero If the initial speed were doubled then the general formula would read: braking distance = 2 * -(initial velocity)^2 / (deceleration) NOTICE that the two equations are the exact same except for the leading coefficients. 1/2 is assocaited with the braking distance of the normal velocity while 2 is assocated with the breaking distance of the doubled velocity. Since 2 is four times larger than 1/2, this leads us to the conclusion that the breaking distance for an object traveling at double a certain velocity would be 4x greater than the breaking distance of the object moving at the "regular" velocity.
Braking distance refers to the distance a vehicle will travel from the point when its brakes are fully applied to when it comes to a complete stop.
The equation that links stopping distance, thinking distance, and braking distance is given by: Stopping Distance = Thinking Distance + Braking Distance. Thinking distance is the distance a vehicle travels while the driver reacts to a hazard, while braking distance is the distance traveled while the vehicle comes to a complete stop after the brakes are applied. Together, they represent the total distance required to stop a vehicle safely.
When the speed of a vehicle doubles, the braking distance is increased by approximately four times. This is because the braking distance is directly proportional to the square of the speed.
The total distance it takes to stop a vehicle traveling at 60 mph depends on several factors, including reaction time and road conditions. On average, a vehicle's stopping distance can be estimated by the formula: stopping distance = reaction distance + braking distance. For a vehicle going 60 mph, the total stopping distance is typically around 180 to 240 feet, which includes approximately 66 feet for reaction time and 114 to 174 feet for braking distance, depending on the braking efficiency and conditions.
On dry, level pavement, with decent tires? About 120 feet. Many things affect this calculation. With worn tires the distance can increase to 210 feet. Dirt roads require longer braking distances than pavement. Ice can increase the braking distance by hundreds of feet. Braking down a hill, depending upon the slope, can double the braking distance, whereas braking up hill can halve that distance. If you lock the tires, you typically increase the braking distance. You can reduce the distance by pumping the brakes. Anti-lock brakes allow the tires to slip, which decreases the braking distance. Extra weight in the vehicle increases the braking distance. Refer to the link below for calculating the braking distance at different speeds with different tire wear on dry, level pavement.
Braking distance
The minimum distance in which a vehicle can be brought to rest in an emergency from the moment that the driver notices danger ahead. Stopping distances of vehicles can be estimated by using the formula: stopping distance = thinking distance + braking distance The thinking distance is the time taken for the driver to react by applying the brakes of the vehicle. This is known as the reaction time, and is about 0.1-0.3 seconds. As a general rule the breaking distance becomes four times greater as the speed of the car is doubled.I found this info athttp://www.tiscali.co.uk/reference/encyclopaedia/hutchinson/m0030390.html
Braking in a moving vehicle is applying the brakes to slow or halt movement, usually by depressing a pedal. The braking distance is the distance between the time the brakes are applied and the time the vehicle comes to a complete stop.
in rain, snow or ice your tires have much less traction, and therefore need more braking distance.
