The speed of the center of the earth as it orbits the sun is v = 107 257 km/h, and the absolute angular velocity of the earth about its north–south spin axis is ω = 7.292(10⁻⁵) rad/s. Use the value R = 6371 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.
