A mass of M=1.0 kg pulls down vertically on a string that unwinds around a solid cylindrical rod attached to a disk, with a combined moment of inertia I=10 kg-m2 . The rod has a radius of r=0.1 m, the disk has or radius R=1m and the system is initially at rest. What is the angular acceleration (in radians/s2 ) of the disk.
