A62 kg skier is moving at 6.5 m/s on frictionless horizontal snow-covered plateau when she encounters a rough patch 3.50 m long. the coefficient of kinetic friction between this patch and her skis is 0.30. after crossing the rough patch and returning to friction free snow, she skis down an icy frictionless hell 2.5 m high. a) how much work is done by friction in crossing the patch? b) how fast is the skier moving when she gets the bottom of the hill? [hint: b) use the conservation of total
