KRAFF, A.V.; VAZQUEZ, G.S.; MIJANGOS, R.R.  e  HEREDIA-CANCINO, J.A.. Obtención y solución a la ecuación de movimiento de un cohete, actuando sobre él las fuerzas externas del campo gravitacional constante y el rozamiento del aire proporcional a la velocidad. Rev. mex. fís. E [online]. 2015, vol.61, n.1, pp.6-10. ISSN 1870-3542.

In this work will be studied the variable mass system for the particular case of rocket problem, with intend obtain the equation that govern its movement and solve after under homogeneous gravitational field conditions and air resistance, know to allow the physics quantities, like velocity and position in all time. Furthermore get the rocket solution for the case that only acts the gravitational force on it, that allows to observe the difference between both solution. The found solution in this paper for this problem doesn't appear in the literature, such that this work purport dazzle the enigmatic solution of rocket problem.

Palavras-chave : Variable mass system; conservation of momentum.
