1. The problem statement, all variables and given/known data
skier decends a slope of 30 degrees. Assume the coefficient of kinetic friction is 0.1

draw a force diagram
find his acceleration
2. Relevant equations



3. The attempt at a solution force diagram i have normal force up, cos(theta)mg down, Force friction left and sin(theta)mg right????

The net force is the vector sum of all the forces as shown in your force diagram. Your force diagram sounds correct from the description you gave, but a drawing would be better.
