Two blocks of mass m1 = 12 kg and m2 = 8 kg are sliding down an inclined plane with a 35-degree angle. (a) If the plane is frictionless, what is the magnitude of the contact force between the two masses? (b) If the coefficients of kinetic friction between m1 and the plane are 𝜇1 = 0.25 and between m2 and the plane are 𝜇2 = 0.25, what is the contact force between the two masses? (c) If 𝜇1 = 0.13 and 𝜇2 = 0.25, what is the contact force?
