Chapter 15, Problem 15-140(choose chapter or problem)
The jet is traveling at a speed of 720 km>h. If the fuel is being spent at 0.8 kg>s, and the engine takes in air at 200 kg>s, whereas the exhaust gas (air and fuel) has a relative speed of 12 000 m>s, determine the acceleration of the plane at this instant. The drag resistance of the air is FD = (55 v2), where the speed is measured in m>s. The jet has a mass of 7 Mg.
