Question

Considering the setup in Figure 2, when the hanger is released to fall, are the statements below correct? The hanger falls at a constant acceleration. The hanger's gravitational potential energy converts to the hanger's kinetic energy and the disk's rotational kinetic energy. The hanger's kinetic energy is always equal to the disk's rotational kinetic energy. The larger the disk's moment of inertia is, the larger the disk's angular acceleration is. The larger the hanger's mass is, the larger the disk's angular acceleration is.
