Hi, I'm trying to find g, or 9.8 m/s^2, with the formula a = w^2 * r. First, I found the value for the angular velocity (2*pi/24 hours) and i converted this to radians per second finding the value 2*pi/86400. I googled the radius for the Earth and got 6,378,100 meters. Finally, i plugged these values into the formula to obtain a centripetal acceleration of 0.0337 m/s^2 which obviously isn't the answer I was looking for. Can someone find the holes in my math or logic? Thanks.
