Sectional Lift/Moment coefficients w/ sinusoidal motion

[spacepirat]

Homework Statement

An airfoil is given by a parabolic camber line, i.e., z=-(a/b^2)*x^2 (where a is a constant and b is the semichord length). Find the sectional lift and moment coefficients taken about the midchord for the airfoil undergoing a sinusoidal motion h = h(bar)sin(wt).

Relevant Equations

z=-(a/b^2)*x^2 (where a is a constant and b is the semichord length)
h = h(bar)sin(wt)

I cannot figure out how to even start this.

Can you post some figures that describe all of the terms that you are using in this question please? Use the "Attach files" button at the bottom of the Edit Window to attach PDF or JPEG files.

Also, what is h? Is it some altitude height? Or something else?

As I said, we can't give you much help until you show more work. But I'll ping @boneh3ad in case he can give you a hint or two for things to look into to start working more on this problem.
