A day on Mars is 24.6 Earth hours long. A year on Mars is 687 Earth days long. How do the angular velocities of Mars’ rotation and orbit compare to the angular velocities of Earth’s rotation and orbit?
w is what I used to represent omega...
Angular velocities are in inverse proportion to periods. I am sure you know what the earth's rotation and revolution periods (P) are.
and similarly for the other question.
I got 1.88 and 1.03 but they are not the answers....
I think I was doing it backwards... will the answers be 0.53 for w(m)/w(e) and 0.98 for w(my)/w(ey)???
w(M)/w(E)= P(E)/P(M) = 23.93/24.6 = 0.973
You are both backwards and upside down. You did not use the formula I gave you.
