Acave 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:
(a) the initially stationary spelunker is accelerated to a speed of 5.00m/s;
(b) he is then lifted at the constant speed of 5.00m/s;
(c) finally he is decelerated to zero speed. how much work is done on the 80.0kg rescuee by the force lifting him during each stage?
