The mass of a rocket when filled with fuel is 2M1 and completely unfueled is M1. The rocket ejects gas in its reference system - M2 is the rocket's current mass, and c is a constant, velocity -c(M2-M1)k^(unit vector in the z direction). The rocket starts off at zero velocity and fully fueled. What velocity can the rocket reach without external force? Hint is given in the figure
