how do i calculate my car's braking distance...?

Question

i want to input mass and speed as variables

Answer 1

You need to check this out if you want to know. It is too complicated to give it to you in an answer.

Answer 2

Braking distance depends on mass and speed, as you correctly state. It also depends on how hard you put your foot down. Here in NZ, as in most civilised countries, we have regular mechanical fitness tests for cars. Here, the testing mechanic puts an accelerometer on the floor of the car, and does an emergency braking check during the test drive. . It tells you how much deceleration your brakes provide. The more the better.

Answer 3

you elect the mass of the vehicle. the speed of the vehicle. And the perspective of the slope, while in comparison with horizontal with gravity. you in addition to mght choose the coefficient of friction between the tires and the line. The deceleration led to by using the friction is comparable to the coefficient of friction (which subsequently relies upon on the sort of highway floor and the sort of tires and the placed on and tear of the tires and the inflation of the tires and the temperature of the tires and probable another stuff) circumstances the conventional stress (that's the stress of straight away down interior the process the gravitational gradient). This stress is only the load of motor vehicle on a flat highway, besides the incontrovertible fact that it truly is comparable to a fragment of that on a slope (reckoning on the perspective of the slope -- you utilize trig to calculate the conventional stress pressing straight away down). to boot, if the slope is up there's a deceleration through gravity and if sloping down their is an acceleration through gravity. those additionally are calculated from the perspective in touch. the foremost equation is: Vot+at^2=D the place D is the gap traveled, Vo is the unique speed, a is the acceleration and t is the time. the subject is that the acceleration a is a mixture of friction and slope, and an algebraic answer demands the thought that acceleration is persevering with with the aid of the struggling with. because of the fact the acceleration is especially a function of the friction between highway and tires, and that's almost impossible to calculate, struggling with distances are oftentimes measured. you additionally could make the calculation using potential words commencing with the kinetic potential of the vehicle at speed, yet if so you nonetheless ought to understand the potential dissipation on the tire/highway interface that's on the subject remember of the friction and the conventional stress. In precis, the equation is complicated and the values just about impossible to calculate except you have try archives from the tires and highway in touch.

Answer 4

why use math when you can do it the fun way? all you do is go to an empty area like a parking lot and stay at the average speed u go at. when u do that have a friend or urself time how long it takes from the point where u pressed the break to where u stop. yay done

Answer 5

if u have the speed and mass of ur car u can determine kinetic energy u just have to know at what speed and mass ur brakes wreck......

Answer 6

Start by determining the (de)celeration so you have some idea of the braking force and friction and then use the acceleration formula.
