A massless string is wound around a solid cylinder that has a radius of 0.37 m and a mass of 78.7 kg. The free end of the string is tied to a block of mass 7.87 kg which hangs straight down. At t = 0, the cylinder is allowed to spin about an axis through its center and the block falls, unwinding the string. Assume that the cylinder spins without friction. What is the angular acceleration of the cylinder? (in rad/s^2) 12. AO 4.42 BO 6.41 CO 9.29 DO 13.47 EO 19.53
