**Educational Text Transcription:**

**Problem Description:**

The circular concrete culvert rolls with an angular velocity of \( \omega = 0.58 \, \text{rad/s} \) when the man is at the position shown. At this instant, the center of gravity of the culvert and the man is located at point \( G' \), and the radius of gyration about \( G \) is \( k_G = 3.2 \, \text{ft} \). 

**Task (Part A):**

Determine the angular acceleration of the culvert. The combined weight of the culvert and the man is 500 lb. Assume that the culvert rolls without slipping and that the man does not move within the culvert.

Express your answer to three significant figures and include the appropriate units.

**Input Area for Answer:**

- \( \alpha = \ \_\_\_\_ \) [Value] [Units]

**Diagram Explanation:**

The diagram illustrates a man standing inside a circular culvert as it rolls. Several dimensions and points of interest are marked:
- The radius of the culvert is 4 ft.
- The distance from the center of the culvert to the man's feet is 0.5 ft.
- The rotational axis is indicated by \( G \).

The culvert is rolling clockwise as depicted by the arrow showing angular velocity (\( \omega \)).

This setup is used to analyze the kinematics of the system and calculate its angular acceleration.
