A weight of $8.00\,\text{N}$ is fastened to the lower end of a spring whose upper end is fixed. Initially, the weight is kept at rest at position X, and the spring is unstretched. The weight is then let go and drops to position Y, which lies $4.00\,\text{cm}$ below X. After oscillating, the weight finally settles at O, which is $2.00\,\text{cm}$ below X. How much energy is lost from the system?
- A$0.04\,\text{J}$
- B$0.08\,\text{J}$
- C$0.16\,\text{J}$
- D$0.32\,\text{J}$
