A skier speeds down a smooth ski slope which is at an angle of θ = 21° with the horizontal. The mass of the skier is 75 kg. Take the downhill direction to be positive and uphill to be negative. What is the net force acting on the skier?

Question

Ok, so I have set up these equations:

Fnet of x=F-mg*sin(theta) and then solve for F

Fnet of y=N-mg*cos(theta) and then solve for N

Are these set ups correct? And to get net force, would I just add the two answers from these?
