i claim this can be solved by choosing an arbitrary value for the
exhaust velocity.
the website was a good one but it doesn't help solving this particu;ar
problem.

Then you are an idiot.

It would take an engine with 1000 kilograms of thrust.

Thrust is force, horsepower is power.

Power equals thrust times velocity and your velocity is zero.

i could post the solution now and thus make you eat your words. i'll
wait a few weeks and hope that someone in the group can find a
solution.
it's pretty basic physics. F*t = m*v

Yeah, right.
