What is the momentum of a proton with 950-MeV total energy?
(Rest energy of a proton is 938 MeV)

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

*Proton speed
The rest energy of a proton is about 938 MeV. If its kinetic
energy is 1071 MeV, find the proton's speed as a ratio of c to 3
significant figures.

(a) How much energy is required to accelerate a proton from rest
to 0.7c? (Rest mass = 938.27
MeV/c2
(b) What is the momentum of the proton once it reaches this
speed? (Express your answer in units of MeV/c.)
(c) Would more, less, or the same amount of energy be required
to accelerate an electron from rest to this speed?

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 kinetic energy of the electron?
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!)
What is the momentum of the electron...

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 is accelerated to a speed where its total energy is
157 times larger than its rest energy.
How many times is the kinetic energy of the electron larger than
its rest energy?
What is the kinetic energy of the electron?
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 a
precision of seven or eight digits!)
What is the momentum...

What is the momentum of a 870-MeV proton (that is, its kinetic
energy is 870 MeV )?

An electron is accelerated to a speed where its total energy is
100 times larger than its rest energy.
1) How many times is the kinetic energy of the electron larger
than its rest energy?
2) What is the kinetic energy of the electron?
3) 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 a
precision of seven or eight digits!)
4)...

A proton moves with a speed of 0.975c.
(a) Calculate its rest energy. MeV
(b) Calculate its total energy. GeV
(c) Calculate its kinetic energy. GeV
