A man can swim in still water with a speed of `2 ms^-1`. If he wants to cross a river of water current speed `sqrt(3) ms^-1` along the shortest possible path, then in which direction should he swim ?

A man can swim in still water with speed v . He wants to cross a river of width d that flows with speed u and reaches the point directely opposite to his starting point. (a) In which direction should he try to swim (i.e., find the angle the makes with the river flow)? (b) much time will he take to cross the river ?

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 swimmer can swim in still water with a speed of 3 ms^(-1) While crossing a river his average speed is 5 ms^(-1) If crosses the river in the shortest possible time, what is the speed of flow of water ?

A swimmer can swim in still water with a speed of 3 ms^(-1) While crossing a river his average speed is 5 ms^(-1) If crosses the river in the shortest possible time, what is the speed of flow of water ?
