mass of an object near the speed of light

[buenos]

I am trying to find the equation that calculates the increased relativistic mass of an object that has been accelerated to near the speed of light. I have found equations that calculate total energy based on rest mass, or ones that calculate based on voltage (only applies to electrons).

What I need is a function/equation:
m_total = f(m0,speed, constants, no-other-variables)

The relativistic mass is given by:

m=m0/sqrt[1-(v/c)^2]

where:
m0 is the rest mass
c is the velocity of ligth
v is the velocity of the object

Thank you.
