I was going to wait a while longer but decided to go ahead and
let you know that the side of the equation you use is used
in determining the amount of thrust and duration of flight
in a combustion based rocket engine.

the picture above that I linked to gave it away on this page.


so in reality in my example that does not have a nozzle
your side of the equation is unecessary as it only allows
a area to focus the thrust in a direction and with adjustable
nozzles can be used to adjust thrust amounts.

ie.. less thrust when less thrust is needed.
more thrust when more thrust is needed.

and of course the m*Ve side of the equation is the same as
the momentum equation and is the only side of the equation that we should use , given we have no nozzle.

I was thinking you would eventually figure that out , but
this has dragged on too long and you never did.



I was just waiting to see if you could / would ever comprehend it Bryan.
