A skier is traveling at a constant speed of 4 m/s on a ski slope. The kinetic coefficient of frictionbetween her skis and the slope is 0.2. Find the angle of the slope.

attempt:

sin feda = f/w but i have no weight

f=mgsinfeda and N=mg cos feda

all of this ends up being mu=tan feda but dont understand where the Velocity in the problem factors in or if since its a constant force and the net sum of a constant moving anything is zero if it does not factor into the equasion at all. i have drawn a vector sum diagram with net sum =0. We worked out one of these in class but he gave us the wieght of the person and the angle. i cant figure out how to do it without those variables.
