energy levels for the states \( \mathrm{n}=1,2 \), and 3 . Ans: \( 9.2 \mathrm{eV}, 37.7 \mathrm{eV}, 84.8 \mathrm{eV} \) 4 A \( 0.50 \mathrm{~kg} \) baseball is confined between two rigid walls of a stadium that can be modeled as a "box" of length \( 100 \mathrm{~m} \). Calculate the minimum speed of the baseball. If the baseball is moving with a speed of \( 150 \mathrm{~m} / \mathrm{s} \), what is the quantum number of the state in which the baseball will be? Ans: \( 6.63 \times 10^{-36} \mathrm{~m} / \mathrm{s}, 2.26 \times 10^{37} \)

It is approximately the temperature at which moleculles in a classical ideal gas would have the same kinetic energy as the fastest-moving electron in the metal.)
