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`

Two swimmers P and Q start swimming from different positions on the same bank as shown in the figure. The swimmer P swims at an angle 90^(@) with respect to the river to reach point A. He takes 120 second to cross the river of width 10m. The swimmer Q also takes the same time to reach the point A. the velocity component of Q along x-axis with respect to ground is K/24. Find the value of K.

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 crosses the river along the line making an angle of 45^@ with the direction of flow. Velocity of the river water is 5(m)/(s) . Swimmer takes 12 seconds to cross the river of width 60 m. The velocity of the swimmer with respect to water will be:

A person, reaches a point directly opposite on the other bank of a flowing river, while swimming at a speed of 5 m/s at an angle of 120^(@) with the flow. The speed of the flow must be

A swimmer starts to swim from point a to cross a river. He wants to reach point B on the opposite side of the river. The line AB makes an angle 60^(@) with the river flow as shown. The velocity of the swimmer in still water is same as that of the water (i) In what direction should he try to direct his velocity ? Calculate angle between his velocity ? Calculate angle between his velocity and river velocity. (ii) Find the ratio of the time taken to cross the river in this situation to the minimum time in which he can cross this river.

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.

A swimmer wishes to reach directly opposite bank of a river, flowing with velocity 8 m/s. The swimmer can swim 10 m/s still water. The width of the river is 480 m. Time taken by him to do so:

A swimmer crosses a river of width d flowing at velocity v. While swimming, he keeps himself always at an angle of 120^(@) with the river flow and on reaching the other end. He finds a drift of d/2 in the direction of flow of river. The speed of the swimmer with respect to the river is :

Two swimmers start at the same time from point A one bank of a river to reach point B on the other bank, lying directly oppostie to point A. one of them crosses the river along the straight line AB, while the other swims at right angles to the stream and then walks the distance, which he has been carried awayby the stream to get to point B. Both swimmers reach point B at the same time. what was the velocity (assumed uniform) of his walking if velocity of both the swimmers in still water is 2.5 km h^(-1) and the stream velocity is 2 km h^(-1) ?
