net force down plane:
gravity-friction
mg*sinTheta-mu*mg*cosTheta
if it is stationary, the force of static fricion has to equal the gravity down the plane, or mgSinTheta
A 12.0 kg object is on a surface that is inclined 30 degrees and the coefficient of friction is 0.65.
Determine the force of static friction if the block remains stationary.
