An airfoil has a lift coefficient and moment coefficient of $-0.35$ and $-0.050$ about quarter-chord at $-6^{\circ}$ angle of attack. The airfoil has lift coefficient and moment coefficient of $0.70$ and $-0.040$ at an angle of attack of $4^{\circ}$ about the same quarter chord. Find the location of the aerodynamic center.
