Homework Statement
Calculate the centripetal acceleration, in units of m/s2, of the Earth in its orbit around the Sun. Assume that the Earth's orbit is a circle of radius 148,022 thousand km.
Homework Equations
v= 2 pi r/ T
Ac = V^2/ r
The Attempt at a Solution
I solve for V and get 29.48 m/s . For T, I use 3.15 x 10^7 seconds, and for r I use 1.48022 x 10^9
When I solve for Ac, I get 5.87 X 10-6 m/s2
I square 29.48 m/s and divide by 1.48022 x 10^9
The answer is 5.85 x 10-3 m/s2. I have no idea where I'm going wrong! I'm more concerned about why my answer is 10-6 when it should be 10-3 . Any ideas?
