Braking force and braking distance
I have found a formula to calculate braking distance in feet : S= v²/64.f
v = velocity
f = tyre adhesion (e.g. 0.5 or 0.8 in respectively wet and dry).
This formula does not incorporate vehicle weight (or vehicle mass for that matter). I assumed that weight has to be taken into account as well. A lighter car can accelerate faster because it doesnt have to haul all that weight around, consequently it should also decelerate faster. So, why does this formula ignore vehicle weight?
