1. A frictionless projectile is fired from the North Pole and is aimed along the prime meridian. It takes six hours to reach its landing point, halfway to the equator. Where does it land? (Give latitude and longitude). If the same projectile were fired from the South Pole under the same circumstances, where does it land? (Give latitude and longitude). Explain.
2. How might the Earth’s climates system be affected if the Earth’s axis of rotation were perpendicular to the plane of its orbit instead of being inclined at 23 ½ degrees?
