Define
= unit vector due east.
= unit vector due north.
Therefore
Part (a)
Because
, therefore
B² + (-2.5)² = 4²
B² = 9.75
B = 3.1225 km
Answer:
Part (b)
As a positive angle (counterclockwise) measured relative to the southern direction, the direction of
is
Answer: 53°, measured counterclockwise from the south.
Part (c)
If
, then
(-B)²+(-2.5)² = 4²
B² = 16 - 6.25
B = 3.1225 km
Answer:
Part (d)
The direction of
relative to the southern direction is
tan⁻¹ (-3.1225/-2.5) = 51.3°, measured clockwise from south.
Answer: 51.3° measured clockwise from the south.
