Popis: The most efficient way to operate a rocket is to increase its exhaust velocity as it accelerates. When this increase is done properly, the final kinetic energy of the rocket is maximized. It is shown that the resulting ‘‘perfect rocket’’ is far simpler to analyze than the traditional constant‐thrust rocket and provides an excellent application of the material taught in all first semester noncalculus physics courses.
