A rocket blasts off from the Earth's surface. During the initial phase of flight, the engine of the rocket burns fuel at a rate α, which creates thrust by expelling exhaust gas downward with velocity β relative to the velocity of the rocket. The thrust from the engine provides an additional upward force on the rocket of magnitude αβ. By Newton's 2nd Law, the equation governing the motion of the rocket while the rocket is burning fuel is
