Hi Idesa149!!

Did you completely check your equations?
You can write
"hv=W+1/2v^2" as:-

"hv=hv₀+1/2mv^2"

Now you see, the threshold frequency(v₀) depends on the frequency of incident light.

And as tiny-tim stated, threshold frequency is fixed for a particular metal. That is, if you incident a light with a lower frequency and that too with a large intensity, a single elctron wouldn't be emitted.
