Two metal disks, one with radius R1 = 2.40cm and mass M1 = 0.800kg and the other with radius R2 = 4.90cm and mass M2 = 1.70kg , 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 1.60kg block is suspended from the free end of the string.
What is the magnitude of the downward acceleration of the block after it is released?
