The velocity of water in a river is `2 kmph`,while width is `400 m`. A boat is rowed from a point rowing always aiming opposite point at `8 kmph` of still water velocity. On reaching the opposite bank the drift obtained is

A ,man wishing to cross a river flowing with velocity u jumps at an angle theta with the river flow. (a) Find the net velocity of the man with respect to ground if he can swim with speed v in still water. (b) In what direction does the boat actually move ? ( c) Find how far from the point directly opposite to the starting point does the boat reach the opposite bank, if the width of the river is d .

The width of a rivers is 25m and in it water is flowing with a velocity of 4m//min . A boatman is standing on the bank of the river . He want to sail the boat to a point at the other bank which is directly opposite to him . In what time will he cross the river , if he can sail the boat at 8m//min . relative to the water ?

A river is flowing steradily with a speed 5 km h^(-1) . A boat man can row with a speed of 10 km h^(-1) in still water. He rows his boat in river at right angles to the bank of river, If width of river is 800 m , (i) how much time the boat man will take to cross the river ? (ii) How far away from a point just opposite to the bank of river he will be reaching there ? (ii) What will be his effective speed gt
