2. A uniform disk of mass M and radius R rolls without slipping as it is pulled by a massless string parallel to the incline's surface which runs over a pulley of mass M and radius R/Z and is then attached M, R/2 to a hanging block of mass M. In this problem, the string does not slip over the pulley. a. Draw the 'ee-body diagrams for the two masses and the pulley. Include coordinate systems in each diagram. b. Write Newton's Second Law in either the translational form (F = ma) or rotational form (r = Ia) as appropriate for each of the three masses. c. Determine the common acceleration of the disk and the block as well as the tension in the left portion of the string pulling on the disk (T1) and the tension in the right portion pulling up on the hanging block (T 2). d. Explain qualitatively why these tensions are not the same. M
