A jet has a speed of 500m/s relative to the air in which it flies and is traveling north. There is a crosswind blowing from west to east at 100m/s. What compas heading does the plane appear to fly toward?

v=√(v(N)² +v(E)²) =

=√ (500²+100²)=510 m/s
tanα= v(N)/v(E)= 500/100=5.
The direction of jet motion makes the angle α =78.7° with east direction
