SUMMARY
The discussion focuses on calculating the relativistic momentum of a particle with mass m resulting from the disintegration of a particle with mass M at rest. Participants emphasize the importance of using conservation laws, specifically conservation of mass-energy and momentum, to derive the momentum of the mass m particle. Key equations include the conservation of mass-energy equation, \( Mc^2 = \frac{mc^2}{\sqrt{1 - \frac{v^2}{c^2}}} + pc \), and the momentum conservation equation, \( 0 = \frac{mv}{\sqrt{1 - \frac{v^2}{c^2}}} + p \). The discussion concludes that the momentum can indeed be calculated using these equations by eliminating the velocity variable v.
