You need to know thw negative acceleration constant, called
deceleration constant. Otherwise, you don't know how quickly the
energy of motion is being dissipated.

When dealing with gravitation, that constant is always nearly the
same. But, with a car, it depends on the quality of the brakes, and
how hard they are applied.
