The centre of mass, or centre of momentum, (CMS) frame is that in which the sum of the momenta (i.e., the total momentum) of all particles is zero. An electron has a kinetic energy K of 1 MeV and is incident on a proton at rest in the laboratory. The goal of this exercise is to calculate the speed of the CMS frame moving relative to the laboratory. (a) Express the initial energies Ee, Ep and initial momenta pe, pp...

3. (10 pts) High energy particle accelerators convert part of the energy of colliding particles into the masses of particles produced in the collisions. Consider a collision of two protons that produces two charged kaons. The mass of the proton is mp- 938.3 MeV/c2, and the mass of each kaon is mK 493.7 MeV/c2. The reaction is a) The total energy (kinetic energy and rest energy) and total momentum is conserved. Suppose one of the protons is at rest in...
