Part A A string is wrapped around a uniform solid cylinder of radius r, as shown in ( Figure 1). The cylinder can rotate freely about its axis. The loose end of the string is attached to a block. The block and cylinder each have mass m. Find the magnitude o of the angular acceleration of the cylinder as the block descends. Express your answer in terms of the cylinder's radius r and the magnitude of the free-fall acceleration g. View Available Hint(s) a = Submit Previous Answers Correct Note that the magnitude of the linear acceleration of the block is 5 9, which does not depend on the value of r.
