SUMMARY
The potential energy increase in a massless spring when a 28.8 kg mass is attached is calculated using the formula PE = 0.5kx², where k is the spring constant of 4800 N/m. After determining the displacement x as 0.0588 meters, the potential energy is found to be 8.3 Joules. The initial incorrect approach of using 0.5Kx²=mg led to confusion, but the correct method confirms the potential energy increase is indeed 8.3 J.
