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 10.0 m. (1) First, the initially stationary spelunker is accelerated to a speed of 4.10 m/s. (2) Then he is then lifted at the constant speed of 4.10 m/s. (3) Finally he is decelerated to zero speed. How much work is done on the 70.0 kg rescuee by the force lifting him during each stage
