The Greeks thought that the sun was the center of the Univesre for plantets like earth to observe it !!!
You can't.
Work = (force) x (distance) .
You can squeeze distance out of the speed, but there's no way to determine the FORCE being used.
If there's no friction and the car is traveling in a straight line, then NO force is needed to keep it going. It just keeps going. (Newton's 1st law of motion.)
Most likely in a shallow sea environment.
