Question

The system is released from rest in the position shown. Calculate the tension T in the cord and
the acceleration a (positive if to the right, negative if to the left) of the 30-kg block. The small
pulley attached to the block has negligible mass and friction. (Suggestion: First establish the
kinematic relationship between the accelerations of the two bodies.)

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?

The diagram below represents a system consisting of two masses: mi=14 kg and m2=40kg, one of them on an incline and the other one hanging. The pulley is massless and frictionless and the cords joining the masses are ideal. The angle of the incline is 0=35°.
