Please use the conservation of energy method to solve, thank you!
![**Problem R14-7:**
A collar of negligible size has a mass of 0.25 kg and is attached to a spring with an unstretched length of 100 mm. If the collar is released from rest at point A and travels along a smooth guide, determine its speed just before it strikes point B.
**Diagram Explanation:**
- **Collar and Spring**: The collar is connected to a helical spring which is anchored at point B. The spring has a stiffness \( k = 150 \, \text{N/m} \).
- **Path**: The collar slides along a smooth, curved guide.
- **Dimensions**:
- The collar starts from point A, which is elevated relative to point B.
- The vertical height from point A to B is 200 mm.
- The length of the spring when the collar is at A is 400 mm.
This setup is typically used to study energy conservation and dynamics in physics and engineering problems.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F89d31404-901c-4cb4-8788-ffc7f5a8d5c1%2F48851d87-f958-4d6c-826b-9e7a6b3b82eb%2Fodjbi4_processed.png&w=3840&q=75)
