Two masses of masses m1 = 4.0 kg and m2 = 1.0 kg are connected by a thread thrown over a block, which is attached to the top of the prism, and can slide along the faces of this prism. The initial speeds of the loads are zero. Find the acceleration of the loads if a = 60°, β = 30°, and the coefficient of friction of the loads on the plane is μ = 0.20. Neglect the mass of the block and the friction on its axis, and consider the thread weightless and inextensible.
