- 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?
