Answers for the Vector Addition Worksheet:
1.  11.7 km at 31 degrees W of N
2.  31.0 km/h at 15 degrees E of S
3.  412 N at 14 degrees north of down
4.  x=9.06 m/s  y = 4.23 m/s
5.  x= 35.1 m, y=71.9 m
6.  x = 86.9 m, y=-23.2 m
7.  x = 0, y=5 m
8.  9.0 km t 19 degrees S of W
9.  563 km/h at 1.64 degrees S of W
10.  16.6 km at 61 degrees
11.  8.9 m/s at -63 degrees or 297 degrees
12.  35 N at -1.7 degrees or 358.3 degrees

Note that your answers may be slightly different due to rounding and you may have found a different angle.  Check to see if your angle is within 90, 180, or 270 degrees of mine.
