A62.0-kg skier is moving at 6.60 m/s on a frictionless, horizontal, snow-covered plateau when she encounters a rough patch 4.60 m long. the coefficient of kinetic friction between this patch and her skis is 0.300. after crossing the rough patch and returning to friction-free snow, she skis down an icy, frictionless hill 2.50 m high.

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2
