A plane if flying at 200 mph with a heading of 45 degrees and encounters a wind of 100 mph from the west. What is the resulting velocity and heading?

  • Trig - ,

    East speed = 100 + 200 sin 45 = 241
    North speed = 200 cos 45 = 141

    speed = sqrt( 141^2 + 241^2) = 279 mph
    tan east of north = 241/141
    so angle east of north = 60 degrees
