Actually, it's not.  The tires do slide against the pavement, a bit, under
maximum braking.

Ok, that I'll buy.

Sure it is, in terms of distance traveled.  Work is force (which is nearly
constant because the coefficient of friction is nearly constant) times
distance; the change in kinetic energy is directly proportional to the work
done on the car.

Or at least that's the way they taught it in my high school <G>
