Question
It takes 23 hours 56 minutes and4 seconds for the earth to make one revolution (mean sidereal day).What is the angular speed of the earth?Assume the earth is spherical. Relative tosomeone on the rotation axis, what is the linear speed of an objecton the surface if the radius vector from the center of the earth tothe object makes an angle of 50.0° with the axis of rotation.The radius of the earth is 6.37×103 km. What is the acceleration of the object on thesurface of the earth in the previous problem?

Explanation / Answer
Period T = 23 h 56 min 4 s
= ( 23 * 3600 s) + ( 56 * 60s ) + 4 s
= 86164 s
Angular speed of earth w = 2( pi ) / T
= 7.2921 * 10 ^ -5 rad / s
