A sled starts from rest at the top of a snow-covered incline that makes a 22∘ angle with the horizontal. After sliding 75 m down the slope, its speed is 14 m/s. Use the work-energy theorem to calculate the coefficient of kinetic friction between the runners of the sled and the snowy surface. 0.33 0.26 0.45 0.15
