one hundred feet directly overhead, a plane and a dirigible start flying due east. If the plane travels three times faster than the dirigible, what is the greatest angle of sight between the two vehicles from your position? Assume the plane passes from sight after 6000 feet.

A plane weighing 220 kN (25 tons) lands on an aircraft carrier. The plane is moving horizontally at 67 m/s (150 mi/h) when its tail hook grabs hold of the arresting cables. The cables bring the plane to a stop in a distance of 84 m. (a) How much work is done on the plane by ...

A novice pilot sets a plane's controls, thinking the plane will fly at 2.50 * 2 to the 2nd power km/h to the north. if the wind blows at 75km/h toward the southeast, what will the plane's new resultant velocity be? use graphical techniques. Are you sure you don't mean the ...
