Question

An electron has a total energy equal to two times its rest energy.

(a) What is its momentum? MeV/c

(b) Repeat for a proton. GeV/c

Answer #1

The total energy of a proton is three times its rest energy.
Find the momentum of the proton in MeV/c units.

An electron is accelerated to a speed where its total energy is
142 times larger than its rest energy.
How many times is the kinetic energy of the electron larger than
its rest energy?

What is the speed of the electron in terms of the speed of
light? (In this part of the problem you have to enter your answer
with seven or eight digits!)

An electron has a kinetic energy K of 1 MeV and is incident on a
proton at rest in the laboratory. Calculate the speed of the CMS
frame (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) moving relative to the laboratory.
(a) Express the initial energies Ee, Ep and initial momenta pe,
pp of the electron and proton respectively (with...
