3. Certain aircraft can be refueled in midair. During this process, large amounts of gasoline (which has a density of 2.7 kg/ gallon) are pumped into the fuel tank of the moving aircraft. If a certain aircraft of mass 15,000 kg has 500 gallons of gasoline pumped into it during the course of 1 minute, how much extra thrust force must it supply to maintain its constant velocity of 270 m/s? Assume that the fuel moves vertically into the tank, so that it has no initial momentum along the direction of motion. Hint: one piece of information above is not necessary to solve the problem.
