You are skiing in ... preparation for a competition. being a dedicated physics student, you happen to have a scale with you. you notice that the mountainside provides you with 346 n of support force. the snow under your wooden skis is fairly wet. how much friction force acts on your skis as you move down the mountain?

Answer: 34.6N


Explanation:


1) The friction force that acts on the skis as you move down the mountain follows the rule:


Friction force = friction kinetic coefficient × Normal force


2) The friction kinetic coeffcient for waxed wood skis on snow is reported in some literature as 0.10.


3) The normal force is given in the statement: 346 N


4) With that you calculate the friction force as:


Friction force = 0.1 × 346N = 34.6N
