Block 1, of mass m_1 = 0.500 kg, is connected over an ideal (massless and frictionless) pulley to block 2, of mass m_2, as shown. Assume that the blocks accelerate as shown with an acceleration of magnitude a = 0.550 m/s^2 and that the coefficient of kinetic friction between block 2 and the plane is mu = 0.400.Find the mass of block 2, m_2, when theta = 30.0^circ.
