I need to make an integral to fine the speed of the earth. Say the radius is 6378137 meters. How would I account for things closer to the axis that have a radius of 0.0001 meters? I don't think I can just take the speed at the radius. So I found that the Earth rotates at 6.963448857E-4 revs/min then I convert that to radians to get 0.000072921065826007 radians/second, the angular speed. To get linear velocity I multiply ω by the radius, but I need to integrate from 0 to r? So would it be ∫ 0.000072921065826007*r dr a=0, b =6378137? I get 1.483237507 × 10^9. Does this seem right?
