Question

A 40 kg skier comes directly down a frictionless ski slope that is inclined at an angle of 10 degrees with the horizontal while a strong wind blows parallel to the slope. Determine the magnitude and diercection of the force of the wind on the skier id a) magnitude od the skier's velocity is constant, b) magitude of the skier's velocity is increasing at a rate of 1 m/s^2 and c) magnitude of the skiers velocity is increasing at a rate of 2 m/s^2.

I need the equations to get me started for each one.
