A thin disk of initial mass M and radius R has a hole of radius r removed. The center of the hole is a distance r away from the center of the disk. Disk R (a) Before doing any calculations, mark on the figure the appoximate position of the center of mass of the object now that it has this hole. (b) Find the exact position of the center of mass of the object.
