Answer to Question #36619 in Mechanics | Relativity for courtney8295
A 65.3-kg skier coasts up a snow-covered hill that makes an angle of 35.0 ° with the horizontal. The initial speed of the skier is 9.64 m/s. After coasting a distance of 2.37 m up the slope, the speed of the skier is 4.00 m/s. (a) Find the work done by the kinetic frictional force that acts on the skis. (b) What is the magnitude of the kinetic frictional force?
