Current Attempt in Progress

A metal strip $8\mathrm{.}25$ cm long, $1\mathrm{.}22$ cm wide, and $0\mathrm{.}744$ mm thick moves with constant velocity through a uniform magnetic field $B=1\mathrm{.}00$ mT directed perpendicular to the strip, as shown in the figure. A potential difference of $3\mathrm{.}48V$ is measured between points $x$ and $y$ across the strip. Calculate the speed $v.$
