 Homework Statement:

A rocket with the initial mass M = Mp + Mf (payload & fuel) rests on a platform and is
ready for launch. It has an engine which ejects a variable propellant mass always with the same
velocity w > 0 downwards, in the moving reference frame of the rocket. Because the propellant
is ejected, the total mass of the rocket changes with time. The rocket can
can only move vertically and is in the homogeneous gravitational field of the Earth.

I tried to use conservation of momentum
I only want to know if the equation I came up with is correct and if not, why?
