Second order nonlinear differential equation of motion in case of rocket in drag-free vertical powered flight under constant thrust is solved by series expansion containing 9 terms; coefficients in series are in terms of given boundary conditions; truncation error of series is estimated, hence accuracy for practical problem based on analysis in paper could be well established; immediate applications are lunar landing and launching; case of constant thrust acceleration is also solved.
