I was curious to what rules Police accident investigation people use to work out the speed of cars before accidents. Also an explanation of how these work would be useful as well.
I have also herd but i don't know how true it is that the coefficient of friction from any make of tyre is about 0.7. What does this mean? and why do more expensive tyres seem to work better even know that they still have coefficient of 0.7.
Any other information about how the accident investigation people work things and how things happened would be useful as well
thanks in advance
