    Rocket Launch: Achieving Escape Velocity w/ Fuel-Mass Ratio of 300

    I'm not completely sure, the problem states m/s. Do you think that, even when considering that ##v'## is relative to the rocket (i.e., measured by someone in the rocket, not an observer on ground), 2.1 m/s would still, anyway, be too small? Thanks for the reply!

    How do you solve the problem of a rocket with variable mass?

    Rocket Launch: Achieving Escape Velocity w/ Fuel-Mass Ratio of 300

    Homework Statement Rockets are propelled by the momentum of the exhaust gases expelled from the tail. Since these gases arise from the reaction of the fuels carried in the rocket, the mass of the rocket is not constant, but decreases as the fuel is expended. Show that for a Rocket starting...
