A 15.0 kg stone slides down a snow-covered hill, leaving point A with a speed of 10.0 m/s. There is no friction on the hill between points A and B(ground), but there is friction on the level ground at the bottom of the hill , between B and the wall. After entering the rough horizontal region, the stone travels 100 m and the run into a very long, light spring with force constant 2.00 N/m. The coefficient of kinetic and static friction between the stone and the hoizontal ground are .20 and .80, respectively. a) What is the speed of the stone when it reaches point B ? b) How far will the stone compress the spring? c) Will the stone move again after it has been stopped by the spring? d) Classify each force acting on the stone as conservative or non conservative.

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 4.90 m/s; (b) he is then lifted at the constant speed of 4.90 m/s; (c) finally he is decelerated to zero speed. how much work is done on the 68.0 kg rescue by the force lifting him during each stage?
