Calculating the peak voltage of a zener diode output

I have a problem with this homework, I have to calculate the peak voltage of the output after stabilizing with a zener diode.

My Input Voltage is Vin = 5V + 0.7Vsin (2pif*t) with f=10kHz

My circuit is a simple regulator with no load resistor. The series resistance is 82 Ohms, Zener voltage is 3V, max. current through the diode is 33.3mA. How can I calculate the peak output ? My problem is the offset created by 5V, wouldnt the Zener voltage be reached immidiately with this configuration ?
