Calculate INERTIAL MASS of proton traveling close to speed of light

[LBRRIT2390]

Homework Statement

A proton is traveling with a speed of v = 2.993x10⁸ m/s. Calculate the value of the inertial mass for this proton. Assume that the speed of light is c = 3.000 x 10⁸ m/s and that the mass of the proton is 1.673 x 10^-27 kg.

Note: Do your calculations to 4 significant figures. Then round off to give an answer good to 3 significant figures. Be sure to include the correct abbreviation for the SI unit.

Homework Equations

M_inertial=gM
where g = 9.80m/s
and M is the Mass of the proton

The Attempt at a Solution

M_inertial=(9.80)(1.673x10^-27
M_inertial = 1.64 x 10^-26 N

Am I correct?

I don't think it is just like u stated .. I can't say that I am sure about it , but I think you should use the relativistic equations for this question ..

Just came across this...you should multiply rest mass by 1/sq rt(1-v²/c²)

try wikipedia for conceptual developments of inertial mass an drelativistic mass...
