A vector A has a magnitude of 3 units and points in the
−y-direction, while a vector B has half the magnitude of A and
points in the +x-direction. What are the magnitude and direction of
the following vectors? Give the directions of each as an angle
measured counterclockwise from the +x-direction.
(a) A + B magnitude____. unit(s) direction____ °
(counterclockwise from the +x-axis)
(b) A − B magnitude___ unit(s) direction___ ° (counterclockwise
from the +x-axis)
(c) B − A magnitude___ unit(s) direction____ ° (counterclockwise
from the +x-axis)
