How fast is the skier moving

Reference no: EM13326924

A 63.0kg skier is moving at 6.55m/s on a frictionless, horizontal snow-covered plateau when she encounters a rough patch 3.55m long. The coefficient of kinetic friction between this patch and her skis is 0.330. After crossing the rough patch and returning to friction-free snow, she skis down an icy, frictionless hill 3.05m high.

How fast is the skier moving when she gets to the bottom of the hill?

How much internal energy was generated in crossing the rough patch?
