A rocket is propelled forward as very high speed gases are ejected out of its back. Which one of the following is the best explanation as to why the rocket is propelled forward? A) The high speed gases push on the rocket as they are ejected and propel it forward. B) The rocket is propelled forward because both energy and momentum must be conserved. c) The rocket is propelled forward due to the conservation of momentum. D Because the gases are pushing against the air, the air propels the rocket forward.
