The copper-tile is a pretty bad tile. It's at -2 Food and thus quite problematic.
It's also a superb tile to settle on with that 3hammer city center.
It also saves at least 5 workerturns by not having to improve the hill which is really nice.
However... That settlement not only misses out on an opportunity to share the corn. It makes it impossible to ever share the corn.
Ideally we want each food source to be reached by at least two cities so that food can be used for growth rather than workers/settlers.
So settlement on copper makes it abit harder to build workers/settlers efficiently.
It's not like it's the most important decision in the game though, pretty close call between the two alternatives.
Regarding whip in York... Maybe a whip one time here for one more quick worker can work out.
It looks to me like a situation where I would rather want to complete it with only chops and slow-build.
In general, whipping down cities which are so slow in growth isn't good.
York is a city that I would rather do some whips in at a much higher pop so that it can utilize the floodplains and regrowth from whips much faster.

@Nick723, there are some merits to thinking that the copper might be a red herring altogether. The map could be played in a completely different way, claiming more land and securing with warriors.
I don't like the proposed western foodless city spot though. If ignoring copper I would rather want to go for something that can reach the pig, or venture out far for the sheep. But in such an alternative history, delaying the settler for city#3 is probably better.
