1)Two metal disks, one with radius r = 2.50 cm and the other with radius R = 5.00 cm are welded together and mounted on a frictionless axis through their common center, as shown below. A string is wrapped around the edge of the small disk, and a box of mass 1.5 kg is tied to the end of the string. The string does not slip on the disk. The box is released from rest and descends downward while the total moment of inertia of two disks is 22.5 kg.cm². Calculate the acceleration of the hanging box after it is released.
