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

A 400 m wide river is flowing at a rate of 2.0 m s^-1 . A boat is sailing with a velocity of 10 m s^-1 with respect to the water, in a direction perpendicular to the river. (a) Find the time taken by the boat to reach the opposite bank. (b) How far from the point directly opposite to the starting point does the boat reach the opposite bank ? ( c) In what direction does the boat actually move ?
