Academics

a skier of mass m is standing on a slope with an angle of elevation Ã¸. After being given a tiny nudge, the skier slides down the slope, grabs a rope at the bottom of the slope, and swings up to a height h. The coefficient of kinetic friction between the skier and the slope is µk.

a) what is the minimum coefficient of static friction required so that the skier is initially at rest at the top of the slope without using his poles?

b) how much energy is lost while the skier slides down the incline?

c) what is the coefficient of kinetic friction?
