SUMMARY
The work required to compress a spring can be calculated using the formula W = 1/2 kx². In this case, the spring constant k was determined to be 800 N/m based on the work done to stretch the spring 3 cm, which required 12 J. For compressing the spring 4 cm, the calculated work is 0.64 J. This calculation is confirmed as correct, utilizing the appropriate spring compression formula.
