Task id11954
A rocket of mass M is accelerated due to the ejection of gases of mass m, M>>m. If the rocket is initially motionless, then, when ejecting gases of mass m, it acquires a kinetic energy of 104 J. How much will the kinetic energy of the same rocket change with the same firing of its engines, if the rocket moved with a kinetic energy of 1010 J?
