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 ight, negative if to the left) of the 27-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.)

A 3.00 kg block (mass 1) and a 5.00 kg block (mass 2) are connected by a light string as shown; the inclination of the ramp is 40.0°. Friction is negligible. What is: (a) the acceleration of the blocks (b) the tension in the string?
Answer the question correctly. Thank you!
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?
