What is the speed of a point on the equator of the Earth due to Earth's daily rotation?(adsbygoogle = window.adsbygoogle || []).push({});

What is the speed of a point at latitude of 45 degrees N?

Can I use the radial acceleration equation:

a = (V^2) / r

or

v = (2*pi*r) / period

where period = 24 hours = 86400s
