whe
* mr = relativistic mass
* mo = mass at rest
* v *= velocity of particle
* c *= speed-o-light = 186,000 miles/sec

For v = 167,700 miles/sec
* mr/mo = 1/ (1 - (167,700^2 / 186,000^2))^0.5
* mr/mo = 1/ (1 - 0.813)^0.5 = 1/ (0.187)^0.5 = 1/ 0.432 = 2.31

So, the mass of the particle at 90% the speed-o-light is 2.3 times
that of the particle at rest. *It doesn't matter what particle. *Maybe
a silver star?

Not correct. It's not quite as simple as e = m*c**2. You must use the
Lorentz transformation.

I didn't use e = m * c^2

Using the same values you have assiged to c and v, the correct
equation would be:

mr = mo/SQRT(1 - v**2/c**2)

That's exactly the same equation I used but with different notation.
It's still the square root:
SQRT(whatever) = (whatever)^0.5

Is there a standard notation or style for arithmetic and
exponentiation for usenet posting? I've been switching around using
different styles almost at random over the years.

I also divided both sides of the equation by mo to get the ratio of
relativistic mass to the at rest mass.

As v = c, mr must = infinity (therefore no mass can reach c)

Yep.
Go FTL (faster than light), and you get a cosmic speeding ticket.
