A62.0-kg skier is moving at 6.50 m/s on a frictionlesshorizontal snow-covered plateau when she encounters a rough patch 3.50 mlong. the coefficient of kinetic friction between this patch and her skisis 0.300. after crossing the rough patch and returning to friction-free snow, she skis downan icy, frictionless hill 2.50 m high.(a) how fast is the skier moving when she gets to the bottom ofthe hill? (b) how much internal energy was generated in crossing the roughpatch?
