In making a science-fiction movie about an asteroid that collides with Earth, a studio constructs a model Earth pivoted at a support fixed at the south Pole and spinning rapidly about the (vertical) south-to-north axis with angular speed ω pointing out of the North Pole. A Model asteroid approaches horizontally and strikes a grazing blow with the model Earth just at the North Pole. Describe the new motion of the Model Earth.
