SUMMARY
The energy profile of a spring is symmetric, as described by the equation for elastic potential energy (EPE), \(E = \frac{1}{2}kx^2\). In the context of the A level physics problem, the maximum EPE occurs at the positions of 0 and 0.8, but not at 0.4, due to the specific conditions outlined in the mark scheme. The discussion clarifies that when a mass is at rest, the spring does not possess elastic potential energy, resolving the confusion regarding the energy states at various positions.
