A yo-yo-shaped device mounted on a horizontal frictionless axis is used to lift a 30 kg box
Question:
A yo-yo-shaped device mounted on a horizontal frictionless axis is used to lift a 30 kg box as shown in Figure. The outer radius R of the device is 0.50 m, and the radius r of the hub is 0.20 m. When a constant horizontal force Fappof magnitude 140 N is applied to a rope wrapped around the outside of the device, the box, which is suspended from a rope wrapped around the Rigid mount hub, has an upward acceleration of magnitude 0.80 m/s2. What is the rotational inertia of the device about its axis of rotation?

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
