A 62.0-kg skier is moving at 6.10 m/s on a frictionless, horizontal, snow-covered plateau when she encounters a rough patch 4.10 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.

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

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

A girl on a sled coasts down a hill. Her speed is 6.0 m/s when she reaches level ground at the bottom. The coefficient of kinetic friction between the sled's runners and the hard, icy snow is 0.052, and the girl and sled together weigh 688 N. How far does the sled travel on the level ground before coming to rest?
