SUMMARY
The forum discussion centers on calculating the speed of a neutron after the decay of Helium-5 into Helium-4 and a neutron. The masses involved are Helium-4 at 6.648 x 10^-27 kg and the neutron at 1.67493 x 10^-27 kg. The momentum of Helium-4 is given as 1.903 x 10^-20 kg·m/s, and the kinetic energy is 2.723 x 10^-14 J. Participants emphasize the importance of using conservation of momentum and energy equations to determine the velocities of both particles post-decay, suggesting that the neutron's speed may require relativistic equations if it exceeds 10% of the speed of light.
