comment Finding a y(x) that satisfies $ y(x) = \int_0^x \! \left(\frac{t} {y(t)+1}\right)^2 \, \mathrm{d}t $
Solving cubic equations by hand is generally not worth the effort. Try 'Solve[y^3/3 + y^2 + y = x^3/3, y]' in Wolfram alpha, and take the real solution.

$T$ is the period of $V(t)$, i.e., that number such that $V(t+T) = V(t)$. So $T=1/60$.

comment Norm of integral operator in $L_2$
$\left\|A\right\|_{2}\le 1$. This can be shown using some integral inequalities and Holder's inequality. I have not been able to show that this bound is tight, unfortunately.
