Answer:
The flag is fluttering in the north-east direction. It shows that the wind is blowing toward the north-east direction. When the ship begins sailing toward the north, the flag will move along the direction of the relative velocity (v
wb
) of the wind with respect to the boat.
The angle between v

and v
b
=90+45
tanθ=
(72+51cos(90+45)
51sin(90+45)
Substituting and solving we get,
tanθ=
50.80

=1.0038
θ=tan
−1
(1.0038)=45.11
0
Angle with respect to the east direction = 45.11−45=0.11
Hence, the flag will flutter almost due east.
