The initial state, in this problem, is of a vehicle moving at a known
speed (an input to the formula; it's a variable, but one that we know
at that point). Friction, viscosity, etc, etc, etc are all handled
elsewhere; these trains are generally way overpowered, and the onboard
computer caps the power and non-emergency braking such that the change
in speed never exceeds 0.85 m/s/s. I don't know how exactly it goes
about that, but for the purposes of this test, we can assume that it's
able to achieve that acceleration.
