You drop a 2 kg book to a friend who stand on the ground at distance d=10.0 m below, if your friends out streched hand at distance d=1.50 m above the ground. (a) how does the work wg does the gravitational force do on the book as it is drop to her hands? (b) what is the change u in the gravitational potential energy of book earth system drop? if the gravitational potential energy u of that system is taken be zero by ground level

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 11.0 m: (a) the initially stationary spelunker is accelerated to a speed of 4.80 m/s; (b) he is then lifted at the constant speed of 4.80 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 78.0 kg rescue by the force lifting him during each stage
