Example 2 (Cont.): A 400-m walk in a<br />
direction of 30 o N of E. How far is the<br />
displacement east and how far north?<br />
N<br />
400 m<br />
<br />
x = ?<br />
y = ?<br />
E<br />
Note: y is the side<br />
opposite to angle 30 0<br />
OPP = HYP x Sin 30 0<br />
y = R sin <br />
y = (400 m) sin 30 o<br />
= + 200 m, N<br />
The y-component y<br />
is:<br />
R y = +200 m
