Asked by Victoria

An Olympic skier moving at 20.0 m/s down a 30.0 degree slope encounters a region of wet snow and slides 145 m before coming to a halt. What is the coefficient of friction between the skis and the snow?
Answered by drwls
Initial K.E. = work done against friction while slowing down
= M g cos 30*mu

= (M/2)*V^2

M cancels out. Solve for mu
