The magnitude of kinetic friction is given as 45.0 N. Kinetic friction is related to the normal force N by f k = \(\mu_{k}\)N; thus, we can find the coefficient of kinetic friction if we can find the normal force on the skier. The normal force is always perpendicular to the surface, and since there is no motion perpendicular to the surface, the ...
