22. A 92.0-kg skydiver with an open parachute falls straight downward through a vertical height of 325 m. The skydiver's velocity remains con- stant. What is the work done by the nonconscrvative force of air resistance, which is the only nonconservative force acting? (a) – 2.93 × 10ʻ J (b) 0 J (c) +2.93 × 10° J (d) The answer is not obtainable, because insufficient information about the skydiver's speed is given.
