4. A uniform hoop rolls without slipping down a 10° inclined plane. What is the acceleration of the hoop's center of mass? The moment of inertia of a uniform hoop about an axis that passes through its center = mr². The moment of inertia of a uniform hoop about an axis that is tangent to its surface = 2mr².
