Assertion:- The magnitude of velocity of two boats relative to river is same. Both boats start simultaneously from same point on one bank They may reach opposite bank simultaneously moving along different straight line paths.
Reason:- For boats to cross the river in same time, the component of their velocity relative to river in direction normal to flow should be same.

Velocity of the boat with respect to river is 10m/s. From point A it is steered in the direction shown. Where will it reach on the opposite bank ?

Velocity of a boat relative to river current and river current velocity are equal in magnitude. Starting from point A on the southern bank, the boatman wants to reach a point B on the nothern bank in north - east from A . In which direction he has to steer the boat?

The velocity of boat relative to water is 4 m/sec . The velocity of water relative to ground is 8m/sec . In what direction boatman aims the boat to cross the river in minimum drift distance method.

The current velocity of river grows in proportion to the distance from its bank and reaches the maximum value v_0 in the middle. Near the banks the velocity is zero. A boat is moving along the river in such a manner that the boatman rows his boat always perpendicular to the current. The speed of the boat in still water is u. Find the distance through which the boat crossing the river will be carried away by the current, if the width of the river is c. Also determine the trajectory of the boat.

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 ?

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

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

Two swimmers A and B start swimming from different positions on the same bank as shown in figure.The swimmer A swims at angle 90^(@) with respect to the river to reach point P .He takes 120 seconds to cross the river of width 10m .The swimmer B also takes the same time to reach the point P
