2) A spool of string of mass M, moment of inertia I about its central axis and radius R falls as it unwinds (the string end is attached to the ceiling). Use energy considerations to find the speed of the center of mass of the spool after a length h of string has unraveled. 2) A spool of string of mass M, moment of inertia I about its central axis and radius R falls as it unwinds (the string end is attached to the ceiling).
