Certainly. There's no built-in function, but the equation for the
Lorentz transform can be defined very simply:
Lorentz[v] := 1 / sqrt[1-v^2/c^2]
You just pass it a velocity less than c.
And then you can just call it. To find out the time dilation factor, at
say, .9 c:
Lorentz[.9 c]
which gives a value of about 2.294. This is the factor by which clocks slow
down, lengths are contracted, or masses increase.
It, of course also works for any velocity:
Lorentz[55 mph]
Applying this properly to the acceleration problem requires defining
which observer measures the acceleration, etc, and whose clock we're looking
at. Another exercise for the reader?
