Question 21 Not yet answered Marked out of 1.00 A 0.0380 kg model rocket is mounted on a nearly frictionless horizontal rail for testing purposes and a 0.0964 kg rocket engine is placed in the model. The rocket engine is designed to give a constant thrust of 13.8 N for the 0.856 s burn, until the mass of the engine is reduced to 0.0080 kg and it flames out. Using momentum to analyze the above scenario is superior to using the Fnet = ma form of Newton's second law mostly because O a. time is a factor. O b. force is not given. O c. acceleration is not given. O d. both the mass and velocity change Question 22 14 C
