what is the time taken by a car to come to rest, after applying the brakes...?

Question

give mathematical calculations please

Answer 1

That would be impossible to answer.
It depends on how fast you were going at the time the brakes were applied... and how hard the brake was applied.... and whether or not you had traditional or anti-lock brakes.
You need to be much more specific.

Answer 2

I don't have a mathematical calculation but the law is that you have to travel one car lenght behind a car for every ten miles per hour you are traveling, which would be about 15-20 feet per 10 miles per hour. The weight of the car would also aid in the equation but probably not much since a brake system is designed to fit the car it's working on. That may be able to help find something more specific.

Answer 3

Like the others have said, it depends. Your car weight, tire size, type of brakes, ABS, weather conditions, type of tire and pressure.

The general rule of thmb is to allow two seconds spacing between cars. Mark a spot on the road and when the car in front of you passes over it, then count 0ne thousand one, one thousand two and when you finish you should be passing over the same sight.

Answer 4

i found something close to what you want..
S=UT+1/2 AT squared

and some boneheads are saying so many feet or car spaces behind per mile an hr...
its basic the same no mater what your speed... count at least 2 ,, 3 is better from where the car in front of you hits a point and when you hit that point

Answer 5

22.7 seconds.

My calculations include a random number for road conditions, coefficient of friction, tire pressure and wear, vehicle weight, brake type and size, payload, wind speed, road pitch and/or incline, aerodynamics & downforce, temperature and driver skill, since ALL of these will affect stopping time.

Any other answer is bull$hit.

Answer 6

that depends on the car, the speed and the brakes... tires too.. you need to include more information
