The speed of the earth's surface located at 2/3 of the length of the arc between the pole which measure from the equator is 232.5 m/s.
Solution:
So the givens are, earth's radius = 6.37X10^6m, and the angular distance from the pole is 90 degrees. So 60 degrees is the 2/3.
r = 6.37x10^6 * cos(60) = 3.185x10^6m
since v = wr
v = 7.3x10^-5 * 3.185x10^6
v - 232.5 m/s
Brazil is the former Portuguese colony in South America is the largest country in the region today. You can tell because they speak Portuguese (Brazilian Portugese to be specific) and it is also the largest country in South America. These clues can help you see that it is Brazil.
