Block A with mass mA = 9.8 kg, and block B with mass m³ =5.3 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 Fr 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. A B ▷ A 25% Part (a) Write an expression for the net force on block A consistent with the positive direction as given in the problem statement.
