Width of a river is 60m . A swimmer wants to cross the river such that he reaches from A to B directly. Point B is 45m ahead of line AC (perpendicular to river) Assume speed of river and speed of swimmer as equal. Swimmer must try to swim at angle `theta` with line AC .If the value of `theta` (in degrees) is `N^(2)` .Find N

Velocity of man w.r.t river is equal to velocity at river value of theta for which man reaches directly at B

A swimmer wants to cross a river from point A to point B. Line AB makes an angle of 30^(@) with the flow of river. Magnitude of velocity of the swimmer is same as that of the river. The angle theta with the line AB should be _________ ""^(@) , so that the swimmer reaches point B.

man wants to swim across a river of which 200 m along the shortest path . If the speed of river stream is 3 km h^(-1) and speed of swimmer in still water is 5 km h^(-1) , then the time of crossing the river is

A swimmer wands to cross a river and reach point B directly from A . The speed of the wimmer in still river and that of river flow are same. The dotted line AN is normal to flow direction of river. For swimmer to reach point B , the angle his velocity relative to river will make with line AN is given by theta . then the value of theta is :

A swimmer crosses the river along the line making an angle of 45^(@) with the direction of flow. Velocity of the river is 5 m/s. Swimmer takes 6 seconds to cross the river of width 60 m. The velocity of the swimmer with respect to water will be :

A swimmer wants to cross a 600 m wide river . If the speed of swimmer is 12 km/hr in still water and speed of river is 6km/hr , along what direction the swimmer must strike in order to cross the river straight ? Also, calculate his resultant velocity and time taken by him to do so .

A swimmer wishes to cross a 500 - m river flowing at 5 km h^-1 . His speed with respect to water is 3 km h^-1 . The shortest possible time to cross the river is.

A man who can swim at a velocity v relative to water wants to cross a river of width b, flowing with a speed u.

A swimmer can swim with 5ms^(-1) in still water. He wants to cross a river having width 200m heading perpendicular to the flow. Speed of flow is uniformly increasing from zero at side to 3ms^(-1) at mid from both side of the river. Then the time taken by the swimmer to cross the river will be
