Block 1, of mass m1 = 0.500kg , is connected over an ideal (massless and frictionless) pulley to block 2, of mass m2, as shown.

Block 1, of mass m1 = 0.500kg , 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= 0.550 m/s^2 and that the coefficient of kinetic friction between block 2 and the plane is μ= 0.400.Find the mass of block 2, m2, when θ= 30.0.
