A particle of mass m has a kinetic energy

A particle of mass m has a kinetic energy of 2mc2 , What are its total energy E and magnitude of momentum p?

 

1. E = 3mc2 , p = 2mc.

2. E = mc2 , p = √ 2mc.

3. E = 4mc2 , p = 4mc.

4. E = 2mc2 , p = 3mc.

5. E = 5mc2 , p = √ 3mc.

6. E = 6mc2 , p = √ 7mc.

7. E = 3mc2 , p = √ 8mc.

 

[Units of the answer will be kg-m/s.] Find the momentum of a particle with a mass of one gram moving with half the speed of light. Answer in units of kg · m/s

 

For this question, I have tried 1.5e5, 1.5e6, and 1.49e5 and none of them are right. Any ideas?
