Answer #1

An electron and positron (anti-electron) has rest energy 0.5
MeV. The two electron and positron traveling in opposite direction
at a speed of 0.99999*ccollide to form a new particle with
a huge mass in the lab.
A) What is the total energy of the two
particles?
B) What is their Kinetic energy at that speed?
C) What is the momentum of the two particles?
D) What is the rest mass of the new particle discovered?

In a head-on collision of an electron of kinetic energy of 2.044
MeV with a positron at rest, the two particles are replaced by two
photons of equal energy. If each photon is traveling at an angles θ
with respect to the electron’s direction of motion, What is the
energy E, momentum p (you can leave the answer in terms of c) and
angle of θ of each photon? (For electron and positron mc2 = 0.511
MeV)

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...

An electron and an antielectron (positron) each have a rest
energy of 0.511 MeV , or approximately 8.2×10-14 J .
When an electron and a positron are both stationary and located
next to each other during an annihilation process, their mass
energy converts to electromagnetic energy released as photons,
electromagnetic particles that have momentum but no mass and that
travel at the speed of light. What is the minimum number of photons
that could be released, and how much energy...

An electron travels at a speed of 8.00 × 107 m/s. What is its
total energy? (The rest mass of an electron is 9.11 × 10-31 kg) in
MeV

1. What is the momentum (p) of a 960-MeV proton (that is, its
kinetic energy is 960 MeVMeV )? Express your answer with the
appropriate units.
2. An electron (mmm = 9.11×10−31 kg ) is accelerated from rest
to speed v by a conservative force. In this process, its potential
energy decreases by 6.70×10−14 J . Determine the electron's speed,
v. (in term of c.)

An electron travels at a speed of 8.80 ×
107 m/s. What is its total energy? (The rest mass of an
electron is 9.11 × 10-31 kg)
answer in MeV. Thanks

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

1. In one inertial reference frame, an electron is observed
traveling with a velocity of magnitude v in the positive
x-direction, where v is 0.6c. What are the momentum and total
energy of the electron in that inertial reference frame in terms of
v and the rest mass of the electron? What are the speed, momentum
and energy of that electron as measured in a reference frame that
is traveling at a velocity of magnitude v/2 in the positive
x-direction?...

An electron (mass m1 = 9.11 x 10-31 kg) and a proton (mass m2 =
1.67 x10-27 kg) attract each other via an electrical force. Suppose
that an electron and a proton are released from rest with an
initial separation d = 3.50 x 10-6 m. When their separation has
decreased to 1.40 x 10-6 m, what is the ratio of (a) the electron's
linear momentum magnitude to the proton's linear momentum
magnitude, (b) the electron's speed to the proton's...
