a 150 lb skydiver is falling in a head first position at a terminal (constant) velocity of 120 mi/h find the force in pounds of the skydiver
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.
