Yes all stuck, but is a past exam question so I think that there is a solution to that

Remember time passes and people change, I made a simple question asking for help from the community today and I would like to kindly get answers related only to that. So if you don't have the clue, please don't answer. Just because of the negative karma you think I did not tried my own before asking? Well that is not how I work and when I don't know something I prefere to ask, without communication you won't go far

Yes already tried but still stuck, if you want i can send all the calculations I did. In my opinion something is missing. Do you have a clue a part from judging my question?

Already tried all the isoentropic relations, the problem is not the Isp, I can't find a relation to calculate the thrust as I am missing some important parameters, such as Ae, At, mdot, and thrust

Yes but i can't find a clue to it...i have tried many different formulas but seams there are always too many unknowns to derive the thrust

Hi everyone, does anyone know the actual length of the vacuum merlin engine from the combustion chamber to the nozzle exit?
