A skier of mass 89kg starts from rest at the top of the hill that is inclined 35 degrees with respect to the horizontal. The hillside is 50m long and the coefficient of kinetic friction between the skis and the snow is 0.25. Using work-energy theorem, calculate the speed of the skier at the bottom of the hill
