Air streams horizontally past a small airplane's wings such that the speed is 70.0 m/s over the top surface and 50.0 m/s past the bottom surface. If the plane has a mass of 600 kg and the TOTAL area of the two wings is 9.00 m2, what is the net vertical force (including the effects of gravity) on the airplane? A. 3930 N B. 4920 N C. 6440 N D. 7390 N E. 9560 N use p(air)=1.0

12. (10 points) Air streams horizontally past an airplane's wings such that the speed is 312.0 m/s over the top surface and 300.0 m/s past the bottom surface. If the plane has a mass of 1.2x10 kg and a wing area of 300.0 m', what is the net vertical acceleration (including the effects of gravity) on the airplane? The density of the air is 1.20 kg/m'. g = 9.8 m/s?. (a) 0.72 m/s? (b) 0.92 m/s? (c) 1.22 m/s2 (d)...

Problem 3. (20 points) Consider the following simplified model of a person in static equilibrium in a yoga pose. The diagram below shows the upward normal forces acting on the hands and feet, as well as the downward weight forces on the upper and lower body. There are also horizontal static friction forces on the hands and feet not shown in this diagram. Assume the weight of the lower body has magnitude 250 N and the weight of the upper...

Using jet backpacks, three astronauts pusn a 110 kg asteroid toward a processing dock. The first astronaut applies F1 = 32 N at theta 1 = 30 degree . the second astronaut applies F2 = 55N at theta 2 = 0 degree , and the last astronaut applies F3 = 41 N at theta 3 = 60 degree as shown. Let the mass of the block Be 8.6 kg and the angle theta = 35 degree for the friction less...
