A model rocket engine has an average thrust of 5.26 N. It has aninitial mass of 24.9 g, whichincludes fuel mass of 12.0 g.The duration of its burn is 1.90 s. (Assume all the fuel isconsumed.)
(a) What is the average exhaust speed of theengine?
m/s
(b) This engine is placed in a rocket body of mass 70.0 g. What is the magnitude of the finalvelocity of the rocket if it were to be fired from rest in outerspace by an astronaut on a spacewalk? Assume the fuel burns at aconstant rate.
