Question
A girl launches a toy rocket from the ground. The engine experiences an average thrust of 5.26 N. The mass of the engine plus fuel before liftoff is 24.9 g, which includes fuel mass of 12.7 g. The engine fires for a total of 1.90 s. (Assume all the fuel is
consumed.)
(a) Calculate the average exhaust speed of the engine (in m/s).
m/s
(b) This engine is positioned in a rocket shell
mass 42.5 g. What is the magnitude of the final velocity of the rocket (in m/s) if it were to be fired from rest in outer space with the same amount of fuel? Assume the fuel burns at a constant rate.
m/s
