In figure, the operational amplifier is ideal and its output can swing between $-15$ and $+15$ volts. The input $v_\rho$ which is zero for $t<0$, is switched to $5$ volts at the instant $\mathrm{t}=0$. Given that the output $v_0$ is $+15$ volts for $\mathrm{t}<0$, sketch on the same diagram the waveforms of $v_0$ and $v_i$. You must give the values of important parameters of this sketch.
