A.) It takes 23 hours 56 minutes and 4 seconds for the earth to make one revolution (mean sidereal day). What is the angular speed of the earth?
B.) Assume the earth is spherical. Relatice to someon in the roation axis, wheat is the linear speed of an object on the surface if the radius vector from the center of the earth to the object makes an angle of 69.0 degree with the axis of rotaion. The radius of the earth is 6.37*10^3 km.
C.) What is the acceleration of the object on the surface of the earth in the previous problem?
