On an essentially frictionless horizontal ice-skating rink, a skater moving at 2.8 m/s encounters a rough patch that reduces her speed by 47 % to a friction force that is 22 % of her weight.
Use the work-energy principle to find the length of the rough patch.

A 55kg ice skater is at rest on a flat skating rink. A 198N horizontal force is needed to set the skater in motion. However, after the skater is in motion, ahorizontal force of 175N keeps the skater moving at a constant velocity. Find the coefficients of static and kinetic friction between the skates and the ice.

A speed skater moving across frictionless ice at 8.5 m/s hits a 5.9 m -wide patch of rough ice. She slows steadily, then continues on at 5.5 m/s What is her acceleration on the rough ice?
A 62.0 kg skier is moving at 6.50 m/s on a frictionless, horizontal snow covered plateau when she encounters a rough patch 3.50 m long
A 62.0 kg skier is moving at 6.50 m/s on a frictionless, horizontal snow covered plateau when she encounters a rough patch 3.50 m long. The coefficient of kinetic friction between this 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?
