“Newton’s Second Law: For every action, there is an equal and opposite reaction.
Blow exhaust out a rocket nozzle at 30,000 MPH (theoretical) and the spacecraft will be propelled to 30,000 MPH, but no more than that.”
PLEASE go back and take your high school physics class again.
That would be NEWTON”S THIRD LAW and it is about FORCE not SPEED.
PLEASE go back and re-read my post #16 where I corrected myself before you even read this thread.
