Question

**Current Attempt in Progress**

If an object has a moment of inertia \( 22 \, \text{kg} \cdot \text{m}^2 \) and rotates with an angular speed of \( 110 \, \text{radians/s} \), what is its rotational kinetic energy?

\[ K_{\text{rot}} = \]

[Input Box] J

---

To solve for the rotational kinetic energy (\( K_{\text{rot}} \)), use the formula:

\[ K_{\text{rot}} = \frac{1}{2} I \omega^2 \]

where \( I \) is the moment of inertia and \( \omega \) is the angular speed.
