Homework Statement
You are given vectors A= 5.1 { i } - 7.0 { j } and vec B= - 3.8 { i } + 7.3{j}. A third vector C lies in the xy-plane. Vector C is perpendicular to vector A and the scalar product of vec C with vec B is 16.0.
Find the x -component and y-component of vector vec C
Homework Equations
Not sure, I have no idea how to find components of C with no angles given. I used the Pythagorean theorem for finding the magnitudes of A and B, however, I do not know how/if that even helps.
The Attempt at a Solution
Ok, for an attempt, I found the magnitude of A to be 8.6023 m while the magnitude of B to be 8.2293 m. I have tried to find C, but I have many different answers I keep getting, all around 5.0 meters, but definitely not right. I finally reached an answer of -2.04 m for the x-component, and it was utterly wrong.
I really need help. thanks. If you need me to clear anything up, just ask.
