  • Solution to your problem has shown in the fallowing explanation section.

Explanation:

  • 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.

  • #v_x=v*cos(30)#

  • #v_x=750*0.866#

  • #v_x=649.5 " "(km)/h#
