A K0 particle at rest decays into a π+ and a π−. The mass of the K0 is 497.7 MeV/c2 and the mass of each pion is 139.6 MeV/c2. What will be the speed of each of the pions?
Two protons traveling at the same speed collide head‑on in a particle accelerator, causing the reaction
p+p⟶p+p+?^0
Calculate the minimum kinetic energy K(min) of each of the incident protons in megaelectronvolts. The ?^0 mass is 135.0 MeV/c2.
