Application Giovanni is flying his Cessna airplane on a heading as shown. His instrument panel shows an air speed of 130 mi/h. (Air speed is the speed in still air without wind.) However, there is a 20 mi/h crosswind. What is the resulting speed of the plane?

  • math -

    x component = 130
    y component = 20

    speed = sqrt (130^2 + 20^2)

    direction
    tan angle up from x = 20/130
