Question 1021742: Earth Travels about the sun in an orbit that is almost circular. Assume that the orbit is a circle with radius 93,000,000 mi. Its angular and linear speeds are used in designing solar power facilities.
a.) Assume that a year is 365 days, and find the angle formed by Earth's movement in one day.
b.) Give the angular speed in radians per hour
c.) Find the linear speed of earth in miles per hour.

You can put this solution on YOUR website! Earth Travels about the sun in an orbit that is almost circular. Assume that the orbit is a circle with radius 93,000,000 mi. Its angular and linear speeds are used in designing solar power facilities.
a.) Assume that a year is 365 days, and find the angle formed by Earth's movement in one day.
---
= (1/365)*360 degs
----------
b.) Give the angular speed in radians per hour
--> 2pi rads/year
1 year = 365*24 hours
-------
c.) Find the linear speed of earth in miles per hour.
Find the circumference of the orbit.
Divide by the number of hours/year.
