Block 1, of mass = 0.650 kg, is connected over an ideal (massless and frictionless) pulley to block 2, of mass. Assume that the blocks accelerate as shown with an acceleration of magnitude = 0.600 m/s^2 and that the coefficient of kinetic friction between block 2 and the plane is = 0.400. Find the mass of block 2, when theta = 30.0 degrees.
