Meriam, Kraige & Bolton — Plane Kinematics of Rigid Bodies: Problem 5_51

5/51 The speed of the center of the earth as it orbits the sun is \( v = 107\,257 \text{ km/h} \), and the absolute angular velocity of the earth about its north–south spin axis is \( \omega = 7.292(10^{-5}) \text{ rad/s} \). Use the value \( R = 6371 \text{ km} \) for the radius of the earth and determine the velocities of points \( A, B, C \), and \( D \), all of which are on the equator. The inclination of the axis of the earth is neglected.
