1. The problem statement, all variables and given/known data How would the weight of a person in some place (48 North and 123 West) change if the rotation rate increased so a day was 3 hours long? 2. Relevant equations F=ma 3. The attempt at a solution The above is not the only equation I think that is needed for this. Not sure about this, but coriolis force maybe needed. I just have no clue about this.
