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...

Notice that m.,- = 139.6 MeV/ca, mp = 938.3 MeV/c. (Tip: in the laboratory reference frame, the proton is at rest. In the center of mass reference frame, ộp = (P2c2 + m 4,P) and Pa- = (1pe2 +m-c, -D)) A photon with energy E = 10 MeV collides elastically...
An electron moves to the right with a speed of 0.82c relative to the laboratory frame. A proton moves to the left with a speed of 0.60c relative to the electron. Find the speed of the proton relative to the laboratory frame. Please show all work.
A reference frame S' moves with a constant speed v=0.800c along the x axis relative to a second reference frame S. A particle is observed from reference frame S' to be moving with velocity 0.400c (along the positive x' axis). What would be the velocity of the particle as measured by an observer in reference frame S?
