An airplane pilot wishes to fly due west. A wind of 80.0 km/h is blowing toward the south. (a) If the airspeed of the plane (its speed in still air) is 320.0 km/h, in which direction should the pilot head? (b) What is the speed of the plane over the ground? Draw a vector diagram.
Explanation:
sinФ = 80km/h / 320km/h
Ф = 14° north of west
Using Pythagorean theorem
√(320km/h )²- (80km/h)²
=310km/h
