SUMMARY
The discussion focuses on the speed of an electron after colliding with an atom, where the electron initially travels at 5.50×106 m/s. The collision excites the atom from its ground state (0 eV) to an excited state with an energy of 3.50 eV. By applying the principle of conservation of energy, the initial kinetic energy of the electron is equal to the sum of its final kinetic energy and the energy transferred to the atom. This establishes a clear relationship between the initial and final speeds of the electron post-collision.
