A string is wrapped around a uniform solid cylinder of radius4.00 cm, as shown in the figure. The cylinder can rotate freelyabout its axis. The loose end of the string is attached to a block.The block has mass 19.9 kg , and the cylinder has mass 10.4kg. a)Find the magnitude of the angular acceleration of the cylinder asthe block descends.(radians/s^2) b)What is the acceleration of the block?(m/s^2) c)What is the tension in the string?
