9-d12The figure shows a tabletop experi-ment that can be used to determine an unknownmoment of inertia. A rotating platform of radiusR has a string wrapped around it. The string isthreaded over a pulley and down to a hangingweight of mass m. The mass is released fromrest, and its downward acceleration a (a > 0) ismeasured. Find the total moment of inertia I ofthe platform plus the object sitting on top of it.(The moment of inertia of the object itself canthen be found by subtracting the value for theempty platform.) Problem 9-d12.

-d12 The figure shows a tabletop experi- nent that can be used to determine an unknown homent of inertia. A rotating platform of radius 2 has a string wrapped around it. The string is hreaded over a pulley and down to a hanging reight of mass m. The mass is released from est, and its downward acceleration a (a > 0) is neasured. Find the total moment of inertia I of he platform plus the object sitting on top of it. The moment of inertia of the object itself can hen be found by subtracting the value for the mpty platform.)
