A 69 kg skier speeds down a trail, as shown in the figure. The surface is smooth and inclined at an angle of θ = 17° with the horizontal.
Help me with an equation to solve. thanks!

(a) Find the direction and magnitude of the net force acting on the skier.
Magnitude
N Direction
perpendicular from the slope (into the ground) perpendicular from the slope (away from ground) downhill, parallel to slope away from the center of the earth towards the center of the earth uphill, parallel to slope
(b) Does the net force exerted on the skier increase, decrease, or stay the same as the slope becomes steeper?
stay the same decrease increase
