**Part B** What is the triangle's kinetic energy if it rotates? Express your answer to two significant figures with appropriate units. - View Available Hint(s) \[ K_{\text{rot}} = \text{Value} \, \text{Units} \] Submit --- **Figure Explanation** The diagram depicts a triangle consisting of three spheres connected by rods. The key elements are: - Each side of the triangle is labeled as 40 cm in length. - Each interior angle of the triangle is noted as 60°, indicating that it is an equilateral triangle. - There is a dot labeled "Axis" at the center of the triangle, suggesting the point about which the triangle rotates. - The triangle’s structure and rotation might be relevant for solving problems related to rotational kinetic energy. **Copyright Information** Copyright © 2023 Pearson Education Inc.
