Homework Help: Drag and Friction

  1. Sep 27, 2005 #1
    I have a question where an 80 kg skier goes down a 40 degree snow slope on wooden skis. The skier is 1.8m tall and .4m wide. I use the drag equation and get 53 m/s. However I am not sure how to add friction into this. Any guidance is appreciated. Oh, friction is .06.

    I am not looking for an answer only direction. The numbers were put down just in case.

    Thank you for your help.

    So the total force downwards (along the slope) must then be - what?
