Homework Help: Velocity relative to ground

  1. Jun 3, 2008 #1
    1. At a particular instant, a stationary observer on the ground sees a package falling with speed v1 at an angle to the vertical. To a pilot flying horizontally at constant speed relative to the ground, the package appears to be falling vertically with a speed v2 at that instant.
    WHAT IS THE SPEED OF THE PILOT RELATIVE TO THE GROUND.


    2. Relevant equations
    Pythagorean Theorem


    3. The attempt at a solution
    I have no idea how to draw this picture up. please help.
    thanks

    draw the velocity vectors of the package and the pilot. the pilot sees the package as is it falls vertically - use that as a connection between their vectors.
