You are right. My mistake. I thought the problem could be simplified only to a conservation of mass. I searched for some equations on the internet and I solved like this: where "m0" is (rocket material + rocket fuel) and "R" is the constant rate of exhaustion. So, m0 = 10 kg and R = 0.225...

Yes. I googled for that. Although they all deal with force and that's not the case of the problem. Or at least, that's what I guess. As I said above, I think it is only a problem of conservation of mass, not momentum. Nevertheless, I will give a second look.

Hi there. I'm new to the forum. I apologize if I'm posting at the wrong session. Anyway, here goes the problem: (sorry for any grammar typos). A solid fuel rocket, home constructed, has initial mass 10 kg; this, fuel is 8 kg. The rocket is launched vertically, from rest; burning the fuel at a...
