Block 1, of mass m1, is connected over an ideal (massless and frictionless) pulley to block 2, of mass m2, as shown. Assume that the blocks accelerate as shown with an acceleration of magnitude a and that the coefficient of kinetic friction between block 2 and the plane is μ.

Find the ratio of the masses m1/m2 .

Express your answer in terms of some or all of the variables a , μ , and θ , as well as the magnitude of the free-fall acceleration g .
