Question:
In the Atwood's machine in Figure, the string passes over a fixed, frictionless cylinder of mass mc.
(a) Find the acceleration of the center of mass of the two-block-and-cylinder system.
(b) Use Newton's second law for systems to find the force F exerted by the support.
(c) Find the tension in the string connecting the blocks and show that F = mcg + 2T.
