Extracted text: A yo-yo-shaped device mounted on a horizontal frictionless axis is used to lift a 23 kg box as shown in the figure. The outer radius R of the device is 1.0 m, and the radius r of the hub is 0.30 m. When a constant horizontal force F аpp of magnitude 100 N is applied to a rope wrapped around the outside of the device, the box, which is suspended from a rope wrapped around the hub, has an upward acceleration of magnitude 0.77 m/s?. What is the rotational inertia of the device about its axis of rotation? "app · Rigid mount Hub R Yo-yo shaped device Rope Number i Units
