So if I just knew that I had an solar irradiance of 100W/m^2 and I needed to power a 1,000,000 W colony how would I determine how large of a solar farm I would need?

Hello everyone, I'm working on a (simplified) Mars energy model in which I need to calculate the area of land I need to cover in solar panels in order to achieve an particular power output.
Say the land I'm looking at receives a constant solar irradiance of 100W/m^2 from...

I see what you saying, I think I'm just confusing myself with the frame of reference. However I don't see how they were able to find the final relative speed (16m/s) using momentum. Could you perhaps explain?
Here is the textbook solution. I can't make sense out of the collision part: They're taking the collision to be completely inelastic which is also confusing me.
