Use the equation mg sin A = umg cos A to determine the angle at which a waxed wood block on an inclined plane of wet snow begins to slide. Assume the coefficient of friction, u, is 0.17.

mg*sin A = u*mg*Cos A
Divide both sides by mg*Cos A:
sin A/Cos A = u
sin A/Cos A = Tan A
Tan A = u = 0.17
A = 9.65o
