Question

A proton moves with a speed of 0.895c.

(a) Calculate its rest energy. _____MeV

(b) Calculate its total energy. ____GeV

(c) Calculate its kinetic energy._____GeV

Answer 1

SOLUTION;

proton move with speed ,v = 0.895c

m= mass of proton =1.67*10-27 kg

A) rest energy of proton is ,E

The rest energy= 393.3 Mev

B)

Now, the kinetic energy KE

Then total energy is

Total energy = rest energy+kinetic energy

  

  

  

a) rest energy = 939.3 MeV

b) total energy= 2.106 GeV

C) kinetic energy = 1.166 Gev
