Question

A proton moves with a speed of 0.850*c*.

(a) Calculate its rest energy.

____________________MeV

(b) Calculate its total energy.

___________________ GeV

(c) Calculate its kinetic energy.

____________________ GeV

Answer #1

speed of proton , v = 0.850c

a) for the rest energy

rest energy of proton = m0 * c^2

rest energy of proton = 1.67 *10^-27 * (3 *10^8)^2/(1.602 *10^-19) * 1 *10^-6

rest energy of proton = 938 MeV

b)

for the total energy

total energy = m* c^2

total energy = 1.67 *10^-27 * (3 *10^8)^2/(1.602 *10^-19) * 1 *10^-6/sqrt(1 - 0.85^2)

total energy = 1781 MeV = 1.78 GeV

the total energy is 1.78 GeV

c)

kientic energy of proton = total energy - rest energy

kientic energy of proton = 1.78 - 0.938

kientic energy of proton = 0.842 GeV

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

A proton moves with a speed of 0.955c.
(a)
Calculate its rest energy.

(b)
Calculate its total energy.
GeV
(c)
Calculate its kinetic energy.

*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.

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

A proton moves with a speed of 0.88c. Find the speed of an
electron that has the same momentum and kinetic energy. (Express
the answer as the quantity of one minus a number times c.)

A proton moves with a speed of 0.66c. Find the speed of an
electron that has the same momentum and kinetic energy. (Express
the answer as the quantity of one minus a number times c.)
same momentum (1- answer) x c
same kinetic energy (1-answer) x c
answer is where the answer would be plugged in, thank you!
