Hi everyone, I am taking a physics course this year and I find myself already looking for help unfortunately. I think I understand the basics of adding vectors using Ax = A cosθ , Ay = A sinθ, etc. I am getting confused with the 3rd leg of the trip though. Since it is due west wouldn't that mean there is no vertical displacement? How can work that into my equation? 1. The problem statement, all variables and given/known data 2. Relevant equations Ax = A cosθ Ay = A sinθ ... R = √Rx2 + Ry2 3. The attempt at a solution I have tried using the previous formulas to solve it but i get an answer of ≈320km. the back of the book says it should be 245km. could someone walk me though this? Thank you!
