vector which has the same direction as the original vec-tor. If, in the equation b = ma, m be a scalar then b has thesame direction as a but its magnitude is m times that of a. 12 ANALYTICAL MECHANICS ILLUSTRATIVE EXAMPLE. A man walks 3 miles N. 30° E., then one mile E., then 3 miles S. 45° E.,then… … Fig. 13. In order to find r analytically we first determine its components. Thus rx = [3 cos (60°) + cos (0°) + 2 cos (-45°) + 4 cos (-90°)+ cos (120°)] miles= (2 + V2) miles= 3.41 miles.ry = [3 sin (60°) + sin (0°) + 2 sin (-45°) + 4 sin (-90°)+ sin (120°)] miles= (2 a/3 -a/2-4) miles= —1.95…
