(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Consider a year to be precisely 365 days. Determine the angular speed of the earth about the sun. If the Earth's mean distance from the sun is 1.496x10^{11}meters and our orbit is circular, determine our orbital speed about the sun.

2. Relevant equations

ω=Δθ/T, where ω is the average angular velocity, Δθ is the distance around a circle (in radians) traveled, and T is the period of orbit.

3. The attempt at a solution

Using the formula mentioned above, I found the angular speed to be 1.99x10^{-7}radians/sec, and I Googled the answer and found that this answer seems to be right (please correct me if I am still wrong). Would the orbital speed be the same idea expressed in a linear fashion (i.e., 29,806.08 m/s)?

Thanks for all your help yet again!
