A 12.0 kg mass is placed on a 25.0∘ incline (θ = 25.0∘) and friction keeps it from sliding. The coefficient of static friction is 0.580 , and the coefficient of kinetic friction is 0.520 . What is the frictional force (if any) acting while the mass is at rest on the incline? (Take up the incline to be the positive direction.) −118 N +73.5 N −27.7 N +49.7 N −55.4 N
