Two metal disks, one with radius r1 = 2.45 cm and mass m1 = 0.900 kg and the other with radius r2 = 5.00 cm and mass m2 = 1.60 kg, are welded together and mounted on a frictionless axis through their common center. a light string is wrapped around the edge of the smaller disk and a 1.60 kg block is suspended from the free end of the string. (a) what is the magnitude of the downward acceleration of the block after it is released? (b) repeat the calculation of part (a), this time with the string wrapped around the edge of the larger disk.
