Four displacement vectors, A,
B, C, and D, are
shown in the diagram below. Their magnitudes
are: A = 16.2 m, B = 11.0 m,
C = 12.0 m, and D = 24.0 m
What is the magnitude, in meters, and direction, in degrees, of
the resultant vector sum of A, B, C, and D?
Give the direction as an angle measured counterclockwise from
the +x direction.
