Question

Marjan, a skier of mass , coasts a distance on level snow to a stop from a speed of , as depicted in the figure. Use the work-energy principle to find the coefficient of kinetic friction between the skis and the snow.What is the initial kinetic energy of the skier? What is the final kinetic energy of the skier?
