[tex]\varepsilon = IR[/tex]

[tex]\varepsilon = -\frac{d \Phi}{dt}[/tex]

[tex]\Phi = BA[/tex]

[tex]-\frac{d \Phi}{dt} = -Bl\frac{dx}{dt} = -Blv[/tex]

So

[tex]\frac{-Blv}{R} = I[/tex]

[tex]\frac{-IR}{Bl} = v[/tex]

Now I plug in and solve, is that right or did I underestimated this question completely?
