Question

A proton moves with a speed of 0.980c. Calculate its rest energy. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. MeV Calculate its total energy. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. GeV Calculate its kinetic energy. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. GeV

Explanation / Answer

a)

For rest energy mc2 I get

E = 938.4 MeV

b)

Total energy = mc2 where = (1 - (v/c)2)-½ = 5.0252 so

total energy = (5.0252)(938.4 MeV) = 4715 MeV

TE =4.71498GeV

c)

kinetic energy is the difference between the two, 4715 - 938.4 = 3777 MeV

KE = 0.3777GeV
