  • we should split the airplane's velocity into two part as vertical and horizontal.

  • the horizontal component has symbolized as green vector(eastward component).

  • We should use our geometry knowledge to calculate magnitude of green vector.

  • vx=v⋅cos(30)

  • vx=750⋅0.866

  • vx=649.5 kmh
