Uniform Circular Motion Problem
Here is(are) the question(s):
"Find the centripetal acceleration for each of the following:
(a) a point on the earth's equator (ignore its orbital motion);
(b) the earth in its orbit around the sun;
(c) the sun's orbit around the center of the Milky Way (period = 2 x 10^8 y; radius = 3 x 10^20 m"
(a) 3.37 x 10^(-2) m/s
(b) 5.9 x 10^(-3) m/s^
(c) 3 x 10^(-10) m/s
I get (a) ac = 2.97 x 10^(-10) m/s^2 which is wrong. What am I doing wrong?
(My work is attached)
Any help would be greatly appreciated!
Thanks in advance!
