2. Relevant equations

General kinetics formulas

3. The attempt at a solution

Actually I don't know how to start. The initial mass is M when qm energy is used the mass is M-m. If I use an energy balance I must use the integral version, right?

[tex] \int m(t) v \mbox{d}v = qm [/tex]

But I don't know how to start.
