Example 11: A bike travels 20 m, E then 40 m<br />
at 60 o N of W, and finally 30 m at 210 o . What<br />
is the resultant displacement graphically?<br />
C = 30 m<br />
30 o R<br />
<br />
<br />
B =<br />
40 m<br />
60 o<br />
Graphically, we use<br />
ruler and protractor<br />
to draw components,<br />
then measure the<br />
Resultant R,<br />
A = 20 m, E<br />
Let 1 cm = 10 m<br />
R = (32.6 m, 143.0 o )
