Hi! I need som hints on what method to use when solving this problem: There is a point on the ground somwhere on the equator. 100 m right above the point a ball is dropped. Where will the ball land? I'm neglecting air resistance and assuming Earths' gravitational acceleration to be constant ~9.8 m/s^2. I've figured these two factors should be of importance: 1. The ball has higher velocity than the point on the ground: it should, following simple rules, land in front of the spot (in the direction of Earths' rotation (eastward)). 2. When the ball moves eastward the direction of Earths' gravitational pull upon it will turn westwards slightly as it is always pointing directly at the centre of the Earth. This will make the ball land further to the west (closer to the point) than predicted if only (1.) was to be considered. How should I proceed? Cheers.
