An ideal massless rope passes over a massless, frictionless pulley. Block A with mass mA=7.2 kg, and block B with mass mB=4.9 kg, are suspended from opposite ends of the rope, as shown. (This contraption is known as an Atwood's machine.) Consider the motion of the blocks after they are released from rest. Let "a" be the magnitude of their acceleration, and let FT be the tension in the rope. Let upward be the positive y direction for block B, and let downward be the positive y direction for block A. What is the numerical value, in newtons, of the tension in the rope?
