A 62-kg skier grips a moving rope that is powered by an engine and is pulled at constant speed to the top of a 23∘ hill. The skier is pulled a distance x = 310 m along the incline and it takes 2.0 min to reach the top of the hill.If the coefficient of kinetic friction between the snow and skis is μk = 0.10, what horsepower engine is required if 30 such skiers (max) are on the rope at one time? P=____hp

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...
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?

In the figure, a T-bar ski tow pulls a skier up a hill inclined at 10.º above horizontal. The skier starts from rest and is pulled by a cable that exerts a tension T at an angle of 30.º above the surface of the hill. The mass of the skier is 60. ke and the effective coefficient of kinetic friction between the skis and the snow is 0.10. 30 (a) Draw the free-body diagram for the skier. (4 pts) 400...
The 1.0 kg block in the figure is tied to the wall with a rope. It sits on top of the 2.0 kg block
1. The 1.0 kg block in the figure is tied to the wall with a rope. It sits on top of the 2.0 kg block. The lower block is pulled to the right with a tension force of 20 N. The coefficient of kinetic friction at both the lower and upper surfaces of the 2.0 kg block is pk = 0.50. (Figure 1) You may want to review (Pages 169 - 172)PART A What is the tension in the rope holding the...
