Sam wraps a string around the inner axle of a 0.130-kg yo-yo. (a yo-yo consists of a small inneraxle sandwiched between two large outer disks). while holding onto the free end of the string, sam releases the yo-yo from rest. as the yo-yo falls, sam holds the free end of the string at afixed distance above the floor. the yo-yo falls with an acceleration of g/6. each outer disk has aradius of 17.0 mm and the inner axle has a radius of 5.00 mm. what is the moment of inertia of the yo-yo? find both an expression and a numerical value.
