A C6-5 model rocket engine has an impulse of 10.0 N⋅s for 1.70 s, while burning 0.0125 kg of propellant. It has a maximum thrust of 13.3 N. The initial mass of the engine plus propellant is 0.0258 kg. What fraction of the maximum thrust is the average thrust? Calculate the relative speed of the exhaust gases, assuming it is constant. Assuming that the relative speed of the exhaust gases is constant, find the final speed of the engine if it was attached to a very light frame and fired from rest in gravity-free outer space.
