In 101104, the latitude of a location L is the angle
Chapter 7, Problem 103(choose chapter or problem)
In 101104, the latitude of a location L is the angle formed by a ray drawn from the center of Earth to the Equator and a ray drawn from the center of Earth to L. See the figure.Linear Speed on Earth Earth rotates on an axis through its poles. The distance from the axis to a location on Earth 30 north latitude is about 3429.5 miles.Therefore, a location on Earth at 30 north latitude is spinning on a circle of radius 3429.5 miles. Compute the linear speed on the surface of Earth at 30 north latitude.
