SUMMARY
The discussion centers on calculating the potential difference required to bring a proton, initially traveling at 3.5×10^5 m/s, to rest by reducing its speed by half. The relevant equations include kinetic energy (KE = 0.5 * m * v^2) and electric potential energy (EPE = q * V). The correct potential difference was determined to be 320 V after applying conservation of energy principles. The user initially miscalculated the potential difference but ultimately arrived at the correct solution with guidance.
