A 60 kg skydiver moving at terminal speed falls 50 m in 1 sec. What power is the skydiver expending on the air? The terminal speed of the falling object is the maximum constant speed the object will reach due to the opposing force of air resistance.

WeighWs = mg = 60kg * 9.8N/kg = 588N. = Weight of skydiver.

P = Fs * V = 588 * 50m/s = 29,400 J/s =
29,400 Watts.
