NASA's Saturn V rockets that launched astronauts to the moon were powered by the strongest rocket engine ever developed, providing 6.77 ✕ 106 N of thrust while burning fuel at a rate of 2.63 ✕ 103 kg/s. Calculate the engine's exhaust speed (in m/s).
Rocket engine models are sized by thrust, thrust duration, and total thrust, among other characteristics. A model C5 rocket engine has an average thrust of 5.26 N, a fuel mass of 12.7 g, and an initial mass of 25.5 g. Fuel burn duration is 1.90 s. The question is:
(a) What is the average exhaust speed of the engine?
(b) If this engine is placed in a rocket body of mass 53.5 g, what is the final speed of the rocket if it is fired into space sidereal? Assume the fuel burns at a constant rate.
