The mechanical work can be defined as:formula_1where formula_2 is the kinetic energy, formula_3 is the force (the thrust of the rocket which is considered constant), and formula_4 is the distance.
: formula_1где formula_2 — кинетическая энергия, formula_3 — сила (тягу двигателя рассматриваем как постоянную), formula_4 — пройденное расстояние.
