A disk with uniform density and radius 0.551 m used to weigh 20.22 kg, but then a hole was punched out. The black arrow in the image above shows the axis of rotation. The hole has radius 00753 m, and has its center 0.103 m away from the center of the disk. What is the înoment of inertia of the disk with a hole? (Hint: only a scientist could call a hole negative mass! Find the mass taken away based on hole size and disk) Answer: Check Choose...
