For H2, a diatomic molecule consisting of two Hydrogen atoms, let's use epsilon=3.18meV, sigma=2.928Angstrom.

1. Tell the story that describes the motion of the atoms for the total energy specified previously. Include comments on the magnitude & direction of velocity. Be specific about what the velocity is for (hydrogen atom 1 or hydrogen atom 2 or both). You can sketch a picture of the molecule with a motion diagram showing a series of velocity vectors for the atoms. Explain your reasoning.

2. If the total energy (K+U) is zero, then what values of r are allowed (neglecting quantum mechanical effects)? This one you should be able to get exactly. Explain reasoning & show work.
