Prob. 15-115-142. The 12-Mg jet airplane has a constant speed of950 km/h when it is flying along a horizontal straight line.Air enters the intake scoops S at the rate of 50 m/s. If theengine burns fuel at the rate of 0.4 kg/s and the gas (air andfuel) is exhausted relative to the plane with a speed of450 m/s, determine the resultant drag force exerted on theplane by air resistance. Assume that air has a constantdensity of 1.22 kg/m³. Hint: Since mass both enters and exitsthe plane, Eqs. 15-28 and 15–29 must be combined to yielddvdm.dm;ΣF, - mVple dt+ vpli dtdtv = 950 km/h%24

A 10.1-Mg truck is resting on the deck of a barge which displaces 209 Mg and is at rest in still water. If the truck starts and drives toward the bow at a speed relative to the barge Vrel = 7.8 km/h, calculate the speed v of the barge. The resistance to the motion of the barge through the water is negligible at low speeds. 209 Mg Answer: v= i 7.8 km/h 10.1 Mg km/h

The 12-Mg truck drives onto the 396-Mg barge from the dock at 17 km/h and brakes to stop on the deck. The barge is free to move in the water, which offers negligible resistance to motion at low speeds.

A jet airliner is cruising at a speed of 900 km/h with each of its three engines discharging air with a velocity of 800 m/s relative to the plane. Determine the speed of the airliner after it has lost the use of (a) one of its engines, (b) two of its engines. Assume that the drag due to air friction is proportional to the square of the speed and that the remaining engines keep operating at the same rate.
