The motion of spinning a hula hoop around one's hips can be modeled as a hoop rotating around an axis not through the center, but offset from the center by an amount h, where h is less than R, the radius of the hoop. Suppose Maria spins a hula hoop with a mass of 0.73 kg and a radius of 0.60 m around her waist. The rotation axis is perpendicular to the plane of the hoop, but approximately 0.38 m from the center of the hoop.(a) What is the rotational inertia of the hoop in this case? kg m^2 (b) If the hula hoop is rotating with an angular speed of 14.1 rad/s, what is its rotational kinetic energy?
