  1. This is a bit of a trick question. At the terminal velocity, the drag force equals the weight, which is 150 lb.
    The NET force on the skydiver at constant velocity is (Weight - Drag) = zero.

    That is all there is to this problem. Pretty easy, hun?

    It is possible to PREDICT the termnal velocity for that person, but this requires a rather more difficult and approximate calculation.
