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.

What is the final velocity of the initial velocity of 25 and -50?

Aperson walks first at a constant speed of 4.89 m/s along a straight line from point a to point b and then back along the line from b to a at a constant speed of 2.95 m/s. what is the average speed over the entire trip?

The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ft⋅lbflbm⋅r(1 psia144 lbf/ft2) = 0.3704 psia⋅ft3lbm⋅r the amount of air that must be added to raise the pressure is lbm
