Ajet aircraft is traveling at 201 m/s in horizontal flight. the engine takes in air at a rate of 44.1 kg/s and burns fuel at a rate of 3.28 kg/s. the exhaust gases are ejected at 669 m/s relative to the aircraft. find the thrust of the jet engine. answer in units of n.

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
