10. A supersonic airplane flies such that the relative speed of the air above the wings it is 400 m / s. The relative speed of the air below the wings is 360 m / s. Determine the difference in pressures acting on the part bottom and top of wings. Assume the heights at the top and bottom of the wings with respect to the Earth's surface are approximately the same.

An airplane has two wings, each with area 5.00 m2, designed so that air flows over the top of the wing at 240 m/s and underneath the wing at 220 m/s. What is the mass of the airplane such that the lift on the plane will support its weight, in 103 kg?. Note. Assume the force from the pressure difference across the wings is directed straight upward. Density of air is 1.29 kg/m3.

1.You are in a plane that flies horizontally with speed 900 km/h ( 250 m/s) when an engine falls off. Neglecting air drag, assume it takes 25 seconds for the engine to hit the ground.     (a) How high was the plane flying?     (b) What is the horizontal distance that the engine covers before hitting the ground?     (c) If the plane somehow continuous to fly as if nothing had happened, where is the engine relative to the airplane...

A frequently quoted rule of thumb in aircraft design is that wings should produce about 1000 N of lift per square meter of wing. (The fact that a wing has a top and bottom surface does not double its area.) a)At takeoff the aircraft travels at 63.0 m/s, so that the air speed relative to the bottom of the wing is 63.0 m/s. Given the sea level density of air to be 1.29 kg/m3, how fast (in m/s) must it...

4. A pilot flying from Honolulu to California flies at an airspeed of 300.0 m/s (“airspeed” = airplane’s speed through the surrounding air) with her airplane pointed 70.0˚ to the east of north. However, the air itself is moving with a 50.0-m/s windspeed blowing due east. When the pilot adds together the two vectors of her airspeed and the windspeed, she gets her groundspeed: the airplane’s actual velocity relative to the ground below. (Even though these are called “speeds” by...

A little confused on these Motion problems: An airplane with a speed of 95.3 m/s is climbing upward at an angle of 38.1 ° with respect to the horizontal. When the plane's altitude is 542 m, the pilot releases a package. (a) Calculate the distance along the ground, measured from a point directly beneath the point of release, to where the package hits the earth. (b) Relative to the ground, determine the angle of the velocity vector of the package...
