1. The problem statement, all variables and given/known data An 60-kg skier is sliding down a ski slope at a constant velocity. The slope makes an angle of 11° above the horizontal direction. (a) Neglecting any air resistance, what is the force of kinetic friction acting on the skier? (b) What is the coefficient of kinetic friction between the skis and the snow? 2. Relevant equations Fr = μ*Nf 3. The attempt at a solution I was able to calculate Nf from the information given as mg*cos(24) or 537.16N. Without knowing the force I was unable to answer the problem. Any ideas where to begin? Thanks!
