Given a moving car's velocity, is it also necessary in practice to know its acceleration to determine how far it will go (a) in the next millisecond and (b) in the next second? Take the initial velocity as exactly 1m/s and the acceleration constant at 1m/s^2. Calculate the distance exactly, in millimeters in (a) and in meters in (b); include all nonzero digits. (As expected, the acceleration is negligible in (a) but not in (b)).
