Prior to take-off, the pilot of a 2930-kg twin-engine airplane tests the reversible-pitch propellers by increasing the reverse thrust with the brakes at point Blocked as shown in the figure. Knowing that point Gis the center of gravity of the airplane, determine the velocity of the air in the two 2.2-meter-diameter slipstreams when the nose wheel A begins to lift off the ground. Assume p 1.21 kg/m and neglect the approach velocity of the air. 2.으 m 1.6 m 2.8 m- 0.3 m m/s. The velocity of the air in the slipstream when the nose wheel A begins to lift off the ground is
