For this question:
http://tinyurl.com/ynkshx
I just use ma=(3000-800)*20 =44kN to get the answer, and the answer is correct.
and haven't make use of
thrust=exhause velocity * dm/dt
or
change in velocity=exhause velocity*ln|initial mass/final mass|
So, just want to confirm am I solved this problem with correct approach, if not, what is the correct solution?
