We all know that the Earth is spherical, and there's only a finite surface area to populate. My question is completely theoretical. How would human civilisations cope in a landscape which was infinte in area. If you could travel in any direction and continue to find new continents and oceans no matter how far you travelled, what would be the effect?

An airplane is flying north at 500km/h. It makes a gradual 180degr. turn at constant speed, changing its direction of travel from north through east to south. The process takes 40s. The average acceleration of the plane for this turn in km/h.s is:
a 12.5 km/h.s, north
b 12.5 km/h.s, east
c 12.5 km/h.s, south
d 25 km/h.s, north
e 25 km/h.s, south


Ok, I know I have a=v^2/r and T=2pir/v to work with.
40 sec = 0.011 hr is half a revolution (180degr) and since T is a hole revolution I think T is 0.0222. Putting that into the equation, I get 1.768km for r.
I tried working the problem backwards by plugging in the answers but I just don't get it. (maybe I'm doing omething wrong with the units since a is normally m/s^2 and thesy give me the answer in km/h.s?)
Also the direction, I would say if you travel north and make a turn east and end up going south, the average direction is east, does that make sense?

I can't seem to figure out where the left most vector starts. I have drawn a diagram, you can view it by going to the following link
