Homework Help: Kinematics Vectors and cartesian coordinates. Plane with wind blowing.

  1. May 22, 2012 #1
    1. The problem statement, all variables and given/known data

    An airplane flies at an air speed of 300 miles per hour, in the direction toward southwest. There is a head wind of 75 mi/hr in the direction toward due east.
    (A) Determine the ground speed.

    (B) Determine the direction of motion of the plane, expressed as an angle counterclockwise from due east.

    2. Relevant equations

    w=wind speed
    V=velocity relative to ground


    *i & j are constants

    direction θ = 180 + arctan|Vy/Vx|

    3. The attempt at a solution

    Totally stumped any help would be greatly appreciated!

    Decompose vector 1 into x & y components, add vector 2, recompose into final vector.
