The pilot of an aircraft wishes to fly due west in a 42.7 km/h wind blowing toward the south. The speed of the aircraft in the absence of a wind is 204 km/h.

  • physics -

    North component of air speed must be 42.7

    If angle west of north is T

    204 cos T = 42.7
    T = cos^-1 (42.7/204)
    T = 78 degrees west of north or 12 degrees north of west
