1. The problem statement, all variables and given/known data What is the linear speed of a point: a) on the equator, b) on the Arctic Circle (latitude 66.5 degrees N), c) at a latitude of 45 degrees N, due to the Earth's rotation? Given Radius (earth)= 6.38x10^6m v? 2. Relevant equations v=rw w= 2pi*f t= 1/f 3. The attempt at a solution I am not sure how go about doing this problem. I wanted to solve for w with 2pi(1/24) but am not sure how to calculate the speed at different areas on Earth.
