A yo yo shaped device mounted on a horizontal frictionless axis is used to lift a 30kg box as shown in figure The outer radius R of the device is 0 50 m and the radius r of the hub is 0 20m When a constant horizontal force of magnitude 152 N is applied in the left direction 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 80 m s What is the rotational inertia I in kg m of the device about its axis of rotation
