A 6.9-kg bowling ball is attached to the end of a nylon (Young's modulus 3.7x10⁹ N/m²) cord with a cross-sectional area of 3.3x10-5 m². The other end of the cord is fixed to the ceiling. When the bowling ball is pulled to one side and released from rest, it swings downward in a circular arc. At the instant it reaches its lowest point, the bowling ball is 1.2 m lower than the point it was released from, and the cord is stretched 3.3x10-³ m from its unstrained length. What is the unstrained length of the cord? Hint: When calculating any quantity other than the strain, ignore the increase in length of the cord. Lo họ họ

Question
![A 6.9-kg bowling ball is attached to the end of a nylon (Young's modulus \(3.7 \times 10^9 \, \text{N/m}^2\)) cord with a cross-sectional area of \(3.3 \times 10^{-5} \, \text{m}^2\). The other end of the cord is fixed to the ceiling. When the bowling ball is pulled to one side and released from rest, it swings downward in a circular arc. At the instant it reaches its lowest point, the bowling ball is 1.2 m lower than the point it was released from, and the cord is stretched \(3.3 \times 10^{-3} \, \text{m}\) from its unstrained length. What is the unstrained length of the cord?
**Hint**: When calculating any quantity other than the strain, ignore the increase in length of the cord.
**Diagram Explanation**:
- The diagram shows a cord fixed to the ceiling with a bowling ball attached at the other end.
- The initial position of the ball is shown on the right side of the diagram.
- \(L_0\) is labeled as the unstrained length of the cord.
- A dashed line represents the vertical distance \(h_0 - h_f\), indicating the height difference of 1.2 m when the ball is at the lowest point.
- The velocity \(v_t\) is indicated by an arrow as the ball swings to the left.
