SUMMARY
The discussion focuses on solving for the final velocity of particle 2 after an elastic collision with particle 1. Particle 1 has mass m and initial speed v, while particle 2 has mass 3m and is initially at rest. The correct final speed of particle 2 is determined to be v1/2, derived from the conservation of momentum and kinetic energy equations. The participants clarify that both momentum and kinetic energy must be conserved in elastic collisions, leading to a system of equations that can be solved simultaneously.
