Components: In the figure, the magnitude of vector is 18.0 units, and the magnitude of vector
is 12.0 units. What vector
must be added to the vectors
and
so that the resultant of these three vectors points in the -x direction and has a magnitude of 7.50 units? Use vector components to find your answer, and express vector
by giving its magnitude and the angle it makes with the +x-axis taking counterclockwise to be positive.
