SUMMARY
The kinetic energy of a proton confined in a one-dimensional potential well with a width of 2.847 x 10-14 m and a mass of 1.67 x 10-27 kg can be calculated using the formula KE = (h2 * n2) / (8 * m * L2). For the quantum number n = 1, the correct calculation yields a kinetic energy of approximately 0.252 MeV. Initial calculations presented in the forum discussion were incorrect, but upon verification, the value was confirmed as 0.252 MeV.
