Thanks, i tried to understand this but it seems a lot of explainations have a tiny error somewhere (including the lecture of my teacher) wich is really annoying to work around. Yours seems to make sense

Like Tomacco (tm), this was smooth and mild.

Very nice video! Please elaborate a little on u(t). It must be referenced to an external observer, but rockets are capable of exhausting fuel with speed relative to their own speed, right?

1:17 WHAT YOU DO??? I don understan. You divide by triangel T. But you no derive M and only say M is dependent of t in the next line. Why didn't you use the product rule and add the derivative of M times v to the equation?
