A skier traveling 9.0 m/s reaches the foot of a steady upward 19 degree incline and glides 12 m up along this slope before coming to rest. What was the average coefficient of friction?
A skier is traveling at a speed of 39.5 m/s when she reaches the base of a frictionless ski hill. This hill makes an angle of 12o with the horizontal. She then coasts up the hill as far as possible. What height (measured vertically above the base of the hill) does she reach? 3.9734 x m
A skier traveling 11.0 m/s reaches the foot of a steady upward 21∘ incline and glides 14 m up along this slope before coming to rest. What was the average coefficient of friction?u= ?
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?

1) A bicyclist is traveling at 25 km/hr when he encounters a 90 m hill. Neglecting road and wind resistance: a) If the hill is going up, what vertical elevation could the cyclist achieve without pedaling? b) If the hill is going down, what speed would the bicyclist achieve without pedaling?
A 90 kgkg ice skater moving at 10.0 m/sm/s on the ice encounters a region of roughed up ice with a coefficient of kinetic friction of 0.360. How far along the rough ice does she go before stopping?
12. A 62 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...
Use the work–energy theorem to solve each of these problems. You can use Newton’s laws to check your answers. A)A skier moving at 4.25 m/s encounters a long, rough, horizontal patch of snow having a coefficient of kinetic friction of 0.220 with her skis. How far does she travel on this patch before stopping? B)Suppose the rough patch in part A was only 2.89 m long. How fast would the skier be moving when she reached the end of the...
A 90 kg ice skater moving at 11.0 m/s on the ice encounters a region of rough up ice with a coefficient of kinetic friction 0.500. How far along the rough ice doe she go before stopping?
