Photoelectric Effect Questions

The photoelectric threshold wavelength of silver is $3250\times 10^{-10}\text{m}$. The velocity of the electron ejected from a silver surface by ultraviolet light of wavelength $2536\times 10^{-10}\text{m}$ is [Given $h=4.14\times 10^{-15}\text{eVs}$ and $c=3\times 10^8{\text{ms}}^{-1}$ ]:
