Homework Statement
A car travels 20.0 km due north and then 35.0 km in a direction of 60(degrees) west of north. Using a graph (that you must construct yourself as the book says... sorry for the inconvenience :/) and find the magnitude and direction of a single vector that gives the net effect of the car's trip. This vector is called the car's RESULTANT DISPLACEMENT.
Homework Equations
You must know the properties of vectors, but even with that knowledge, I can't seem to find the answer. The ANSWER SHOULD BE 48 km. Can someone explain to me why?
The Attempt at a Solution
I added vector A with vector B and got about 55 km. Why am I wrong? Am I missing something?
