Two blocks with masses m1 = 1.4 kg and m2 = 6 kg are attached to a rope that passes through a pulley system as in the picture (the mass of the pulley, the mass of the rope, and the friction of the pulley are ignored). Block m1 is on a table with a smooth surface. The amount of tension in the rope is ... N. Use g = 10 m/s^2.
