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?

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 ?

To take the boat away from the bank of a river, the boatman pushes the bank with an oar. Why?

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 ?

Velocity of the boat with respect to river is 10 m/s. From point A it is steered in the direction shown to reach point C. Find the time of the trip and distance between B and C

Width of a river is 30 m, velocity is 4 m//s and rowing velocity is 5 m//s (a) Make the velocity diagram for crossing the river in shortest time. Then, find this shortest time, net velocity of boatman and drigt along the river. (b) Can the boatman reach a point just oppsite on the other shore? If yes then make the velocity diagram, the direction in which the should row his boat and the time taken to cross the river in this case. (c) How long will it iake hom to row 10 m up the stream and then back to his starting point?

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 compnonet of their velocity relative to river in direction normal to flow should be same.

A river is flowing from west to east with a speed 5 m s^(-1) . A swimmer can swim in still water at a speed of 10 m s^(-1) . If he wants to start from point A on south bank and reach opposite point B on north bank. In what direction direction should he swim ?

A man can row a boat with 4km/h in still water, if he is crossing a river where the current is 2 km/h. (a) In what direction will his boat be holded, if he wants to reach a point on the other bank, directly opposite to starting point? (b) If width of the river 4km, how long will the man take to cross the river, with the condition in part (a)? (c) In what direction shou ld he heat the boat if he wants to cross the river in shorest time and what is this minimum time? (d) How long will it take him to row 2 km up the stream and then back to his starting point?

At a harbour, a boat is standing and wind is blowing at a speed of sqrt(2)m//sec. due to which , the flag on the boat flutters along north - east. Now the boat enters in to river, which is flowing with a velocity of 2m//sec . Due north. The boat starts with zero velocity relative to the river and its constant acceleration relative to the river is 0.2m//sec^(2) due east. In which direction will the flag flutter at 10 seconds ?
