... 25. The linear speed of a point on Earth’s surface depends on its distance from the axis of rotation. To solve for the linear speed, we use v = r, where r is the radius of its orbit. A point on Earth at a latitude of 40° moves along a circular path of radius r = R cos 40°, where R is the radius of ...
