A skier travels down an inclined trail at 22o and the coefficient of kinetic friction for the skier's shoes-ice surface is .2. Compute the skiers acceleration down the hill. (Start with free body diagram for the skier, add a coordinate system and then write the equations for the summation of forces acting on the skier).
