**Physics Problem: Pulley and Crate System**

**Pulley Details:**
- Pulley \( A \) has a weight of 30 lb.
- Centroidal radius of gyration \( k_B = 0.40 \) ft.
- Refer to Figure 1 for a visual representation.

**Problem Statement: Part A**
- **Objective:** Determine the speed of the 12-lb crate \( C \) at the instant \( s = 10 \) ft.
- **Initial Conditions:** The crate is released from rest when \( s = 5 \) ft.
- The pulley at \( P \) rolls downward on the cord without slipping.
- For calculations, neglect the mass of the pulley and the cord as it unwinds from the inner and outer hubs of pulley \( A \).

- **Required:** Express the answer to three significant figures and include appropriate units.

**User Input:**
- Attempted solution: \( v_C = 8.51 \) ft/s
- Result: Incorrect, with 5 attempts remaining.

**Graphical Diagram Description:**
- The figure displays a pulley system.
- Pulley \( A \) shows dimensions:
- Internal radius: 0.4 ft
- External radius: 0.8 ft
- Crate \( C \) is suspended by a cord attached to the pulley, positioned 0.2 ft from point \( P \).

**Instructions:**
- Attempt calculations again and submit correct results in specified units.
- Return to the assignment page or provide feedback as needed.
