Hi Everyone.
I have a question for you all that is most definitely not homework - Its over 20 years since I was at school and sadly I can't remember very much of what our maths teacher told us... hence the reason I'm here!
I work for a company that does off-road vehicle modifications, these modifications add to the weight meaning that the braking distance is increased.
For many years we have been testing the vehicles using a brake tester that reports the deceleration force in "Negative g"
However we now have a customer who wants us to report the stopping distance - Easy if you can measure it which is what we've been doing.
However, I can't help thinking there must be a relationship between the vehicle's weight, starting speed, the "negative g" deceleration and the stopping distance.
So, if the vehicle weighing 3900kg is traveling at 40km/h and we achieve a deceleration force of 0.9g, what will the stopping distance be? How can I calculate it for other vehicle weights?
Answers in metric please as I'm in Australia! I'm not an engineer and I don't have many qualifications so please excuse the lack of an attempted solution.
