Compute the all part of given question:

Question: Two metal disks, one with radius R1 = 2.50cm and mass M1 = 0.900kg and the other with radius R2 = 4.90cm and mass M2 = 1.65kg, 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 1.40kg block is suspended from the free end of the string.

Part I: What is the magnitude of the downward acceleration of the block after it is released? Take the free fall acceleration to be 9.80m/s2.

Part II: Repeat the calculation of part (a), this time with the string wrapped around the edge of the larger disk.

I need expert help to solve the above questions and take the free fall acceleration to be 9.80m/s2.
