A yo-yo-shaped device mounted on a horizontal frictionless axis is used to lift a 37 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 0.33 m. When a constant horizontal force F→app of magnitude 160 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 0.98 m/s2. What is the rotational inertia of the device about its axis of rotation?
