Answer:
When the boat is stationary, the flag
flutters along N-E direction. This shows that velocity of the wind is along N-E
direction. When the boat moves, the flag flutters along the direction of
relative velocity of wind w.r.t the boat. Thus wind velocity
due N-E
direction
Boat velocity due
north
Fig. 4.106
Relative velocity of wind w.r.t.
boat is given by
Clearly, the flag will flutter
in the direction of on
the mast of the moving boat.
Angle between and
If makes
angle with then
or
Angle w.r.t east direction
Hence the flag will flutter almost in
the east direction.
