Homework Help: Rocket propulsion help

  1. Nov 8, 2003 #1
    How do you go about finding the height reached by a rocket with a changing rocket mass if you know the specific impulse, the mass ratio (original mass/final mass) and the thrust to weight ratio? Any help you can give is greatly appreciated.

    edit: I would show you my work on this problem but the honest truth is I do not know where to begin.

    What equations do you have that you think *might* apply?
