You haven't given all of the INFO:
1. Is the skier coasting down hill?
2. Is she being pulled up hill at constant speed?
If the mass of the skier is 50 kg, what is the magnitude of the force of kinetic friction on the skier? Be sure to show your work, and use g = 10 m/s^2 for the magnitude of acceleration due to gravity.
Sin 30degrees = 1/2 Cos 30degrees = square root 3/4 Tan 30degrees = square root 1/3
I think because the skier is on a slope, there needs to be a force vector broken into components to answer this. Not sure what to do.
