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 A

A

A

...

R = √R

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!

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 A

_{x}= A cosθ , A_{y}= 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?## Homework Statement

A

_{x}= A cosθA

_{y}= A sinθ...

R = √R

_{x}^{2}+ R_{y}^{2}## The Attempt at a Solution
