Imagine that it is possible to travel to each planet in our solar system. After a space “cruise," a tourist returns to Earth. One of the ways he recorded his travels was to weigh himself on each planet he visited. Use the list
of these weights on each planet to figure out the order of the planets he visited. On Earth he weighs
720 newtons. List of weights: 655 N; 1,699 N; 806 N; 43 N; and 662 N.

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
