372204 A rocket with an initial mass \(m_{0}\) is going up with a constant acceleration a by exhausting gases with a velocity \(v\) relative to the rocket motion, then the mass of the rocket at any instant of time is (assume that no other forces act on it)

372205 A rocket is intended to leave the Earth's gravitational field. The fuel in its main engine is a little less than the amount that is necessary and an auxiliary engine, (only capable of operating for a short time) has to be used as well. When is it best to switch on the auxiliary engine?

372206 A \(600 \mathrm{~kg}\) rocket is set for a vertical firing. If the exhaust speed is \(1000 \mathrm{~ms}^{-1}\), the mass of the gas ejected per second to supply the thrust needed to overcome the weight of rocket is

372207 If the force on a rocket moving with a velocity of \(300 \mathrm{~m} / \mathrm{s}\) is \(345 \mathrm{~N}\), then the rate of combustion of the fuel is
