An airplane is flying with a constant altitude at a speed of 475 mph in a direction 25° north of west directly towards its final destination. The airplane then encounters wind blowing at a steady 30 mph in a direction 85° north of east. Yes a. Start by drawing a vector diagram for this situation. Did you draw a diagram? Great! Your diagram might look something like this: Wind New Path Original Path b. If the pilot does not correct...

When an airplane is flying 200 mph at 5000-ft altitude in a standard atmosphere, the air velocity at a certain point on the wing is 273 mph relative to the airplane. Please provide the gage pressure (units of lb per square feet) at the location on the wing where the wind speed (from the perspective of the wind) is 273 mph. Provide your answer with two significant figures.

An airplane flying at 450kt crosses in front of another airplane flying at 350kt. The directions of motion of the two airplanes with respect to the ground are perpendicular. (a) Calculate the relative velocity of the faster airplane with respect to the slower one. (b) Calculate the relative speed of the two airplanes. (c) At what angle with respect to their direction of motion will the pilots of the slower airplane see the faster one move?

An airplane encountered a head wind during a flight between Joppetown and Jawsburgh which took 4 hours and 42 minutes. The return flight took 4 hours. If the distance from Joppetown to Jawsburgh is 2400 miles, find the airspeed of the plane (the speed of the plane in still air) and the speed of the wind, assuming both remain constant. mph. The speed of the plane is mph and the speed of the wind is (Round to one decimal place...
