SUMMARY
The discussion focuses on calculating the velocity and momentum of an electron with a rest mass of 0.511 MeV and a kinetic energy of 10.0 MeV. The initial attempt using the formula for momentum, sqrt(2KEm), resulted in an invalid velocity exceeding the speed of light. The correct approach involves using the energy-momentum relation, Rest E + KE = sqrt(m²c⁴ - p²c²), which led to complications with negative roots. Ultimately, the participant resolved the issue independently.
