SUMMARY
The discussion centers on calculating the speed of a proton accelerated through a 500V electric potential difference. The correct approach involves using the relationship between electric potential energy and kinetic energy. The energy gained by the proton is equal to the charge of the proton multiplied by the potential difference, resulting in a kinetic energy of 8.0E-17 J. This energy translates to a speed of approximately 3.1E5 m/s, as confirmed by the professor. The initial attempt to calculate the speed using distance and time was incorrect due to a misunderstanding of the relevant equations.
