Me neither. Didn't take it. But have come across something called 'kinetic energy' (energy of movement) that is quantified by the formula K.E. = 1/2 Mass times Velocity Squared. The question often comes up on RV forums about how fast people drive their rigs and disagreements ensue. Just saying . . . Do the math.
And the force your brakes exert is a very complex formula that boild down to Mass times constant.
Thus stopping distance, no matter if you are driving a Mini-Cooer or a 160,000 pound steel hauler.. From the moment the wheels lock up (Note below) is a matter of Speee*Speed/(Coefficient of friction*Constant)
On the ideal REFERENCE surface this means
10 MPY 5.5 feet
20 MPH 22 feet
40 MPH 88 feet
((Speed/10)Squared tunes 5.5)
Of course you will almost never be on the Reference road so your ractual stopping distance may be more or less.
