Two blocks of mass m₁and m₂are sliding down an inclined plane (Fig. P4.79). 

(a) If the plane is friction less, what is the magnitude of the contact force between the two masses? 

(b) If the coefficient of kinetic friction between m₁ and the plane is µ₁ = 0.25 and between m₂ and the plane is µ₂ = 0.25, what is the contact force between the two masses? 

(c) If m₁ = 0.15 and m₂ = 0.25, what is the contact force?
