Question 1005358
According to the Theory of Relativity, and as represented by the equation below, the mass of a particle changes with its velocity. When is the rational expression of the equation undefined? (Think of the fraction in the denominator as a single variable.)

**m0 means m with a subscript of 0**

{{{m^2=(m0^2/(1-v^2/c^2))}}}
m0=rest mass
v=velocity
c=speed of light
------
Undefined when (v^2/c^2) = 1
----
v/c = 1
-----
v = c (velocity of the particle = the speed of light)
