(a) A skier is accelerating down a 30.0° hill at a = 4.40 m/s2 (Fig. 3-36). What is the vertical component of her acceleration?
_______ m/s2 down.

I dont' get what to do with the acceleration. Would I be using the sin, cos, and tan stuff?

You are suggesting the correct approach. The vertical component of her acceleration will be the component that is pointed straight down.

sin (30) = opposite over hypotenuse

in this case the hypotenuse is the total acceleration 4.4 m/s^2

Drawing a picture is key to understanding these problems.

Vertical component is 4.40cos60, or 4.40sin30, both of which give 4.40*0.5 = 2.20m/s2.
