Question

3. Two boats move with constant velocities on a wide river. The flow velocity of the
river is constant, uniform and parallel to the shoreline. The given figure is an
aerial photo, which gives the top view of the situation at an instant of time. The
position of one of the boats is marked with a square and the other with a
triangle. The stars represent position of litter fallen from the boat. One of the
boats departed from the point A.
a) Which ship departed from which shore?
[2 marks)
b) In which direction does the river flow?
(1 mark)
c) Mark roughly the point from which the second boat departed. (A rough idea of
the position of the point with some explanation will do and score the marks.
However, you are welcome to be more accurate if you can.)
(1 mark)
Hint: Solve the problem geometrically.​

Answer 1

Answer:

Here's your answer!

Explanation:

Boat A appears to move normal to the flow of river with relative to an observer moving with river current ,it mean Boat A has a velocity component along river flow ,hence its velocity will appear more than of B from ground.
