1. The problem statement, all variables and given/known data The question is self developed. After the lecture from our professor over Coriolis Effect, we decidable to be over ambitious and derive the equation and somehow calculate the force exerted on a given location on the earth or "For example we throw a ball in a train travelling opposite the direction of the Coriolis effect - But someone said that would be possible if it is going inside down the Earth (Somebody can correct me If I am wrong) 2. Relevant equations 3. The attempt at a solution We have not attempted but just drived to get the general equation and read several pages about it. I would like someone to attach some notes for Coriolis effect and put us in the right direction ! I would also like if someone gives us a question to solve, a exciting question, through which we can learn in detail the application of Coriolis effect.
