Hi. I needed help answering two questions regarding the following circuit (see pic related)

>1) Derive an expression for Ro.
I tried this one myself. I got Ro = R2||R3. R1 is in parallel with a short circuit so I didn't include that. I short circuited the voltage source because we're finding the output resistance.

>2) Draw the Thevenin equivalent circuit as seen by the load resistor (assume Vs = 5V)
Am I supposed to remove the load resistor and use Thevenin's theorem? How would I do that if I don't know Rs? Can I assume Rs = Ri (input resistance)?

Thanks

By the way, the instructions say to treat Rs as a short
