A cave rescue team lifts an injured spelunker directly upward and out of a sinkhole by means of a motor-driven cable. The lift is performed in three stages, each requiring a vertical distance of 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 3.60 m/s; (b) he is then lifted at the constant speed of 3.60 m/s; (c) finally he is decelerated to zero speed. How much work is done on the 63.0 kg rescue by the force lifting him during each stage?
