A 92.0-kg skydiver with an open parachute falls straight downward through a vertical height of 325 m. The skydiver's velocity remains constant. What is the work done by the nonconservative force of air resistance, which is the only nonconservative force acting?
(a) - 2.93 × 105 J
(b) 0 J
(c) + 2.93 × 105 J
(d) The answer is not obtainable, because insufficient information about the skydiver's speed is given.
