52. On the table is a smooth bar of mass m = 4 kg. By bar tied two cords thrown over fixed units attached to opposite edges of the table. By the end of the cord suspended weights whose masses m1 = 1 kg m2 = 2 kg. Find the acceleration a, which moves the bar, and the power of the T of each of the tension cords. Unit weight and friction neglected.
