The Earth has a radius of 6.38 x 106 m and turns on its axis once every 23.9 h. (a) What is the tangential speed (in m/s) of a person living in Ecuador, a country that lies on the equator? (b) At what latitude (i.e., the angle in the figure, in degrees) is the tangential speed 1/4 that of a person living in Ecuador?
From the question I got help with earlier, I think I know how to go about this, but I want to make sure.
use the equation v=d/t where d= 2[tex]\pi[/tex]r and r=6.38x106
I then convert the 23.9 hours into seconds and divide the d found above by the seconds
To find the latitude I have to find [tex]\theta[/tex] in this picture that I am not sure how to post here...
Question is, do I need to convert the radians to degrees to find [tex]\theta[/tex]?
Thank you!
