Physics

An aircraft has a cruising speed of 100 m/s On a particular day, a wind is blowing from the west at 75.0 m/s
If the plane is pointed due north, what would be the magnitude and direction of the velocity relative to the ground?
If the pilot wishes to have a resultant direction of due north, in what direction should the plane be pointed?

  1. X = 75 m/s.
    Y = 100 m/s.

    Q1. tan A = Y/X = 100/75 = 1.33333
    A = 53.1o

    V=Y/sin A = 100/sin53.1 = 125.0N.[53.1o]

    Q2. Direction = 90o-53.1o=36.9o W of N.
