Earth travels around Sun in 1 year in the orbit which is almost circular. Suppose that orbit is the circle with the radius of 93,000,000 mi. Its angular and linear speeds are used in designing solar-powered facilities.
A. Suppose that the year is 365 days, and compute angle formed by Earth's movement in one day.
B. Provide angular speed in radians per hour.
C. Determine linear speed of Earth in mph.
