Person aiming to reach the exactly opposite point on the bank of a stream is swimming with a speed of `0.5ms^(-1)` at an angle of `120^(@)` with the direction of flow of water.The speed of water in the stream is

A person aiming to reach the exactly opposite point on the bank of a stream is swimming with a speed of 0.5(m)/(s) at an angle of 120^@ with the direction of flow of water. The speed of water in the stream is

A person aiming to reach exactly opposite point on the bank of a stream is swimming with a speed of 0.6 m/s at an angle of 120^(@) with the direction of flow of water . The speed of water in the stream is

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 man can swim at a speed 2ms^(-1) in still water. He starts swimming in a river at an angle 150^(@) with direction of flow of water and reaches at the exactly oppsite point on the opposite bank. (a) Find the speed of flowing water. (b) If width of river is 1 km then calculate the time taken also

A man who can swin at the rate of 2 (km)/hr) (in still river) crosses a river to a point exactly opposite on the other bank by swimming in a direction of 120^@ to the flow of the water in the river. The velocity of the water current in (km)/(hr) is

A swimmer wishes to reach directly opposite point on the other bank of a river,flowing with velocity 4sqrt(2)m/s .The swimmer can swim with 8m/s in still water.The angle with the flow direction he should swim to reach the directly opposite point is (A) 45^(0) (B) 90^(0) (C) 135^(0) (D) 150^(0)

A man can swim in still water at a speed of 6 kmph and he has to cross the river and reach just opposite point on the other bank.If the river is flowing at a speed of 3 kmph ,and the width of the river is 2km , the time taken to cross the river is (in hours)

A launch travels across a river from a point A to a point B of the opposite bank along the line AB forming angle prop with the bank. The flag on the mast of the launch makes an angle beta with its direction of motion. Determine the speed of the launch w.r.t. the bank. The velocity of wind is u perpendicular to the stream. .

A house pipe lying on the ground shoots a stream of water upward at an angle 45^(@) to the horizontal at a speed of 20ms^(-1) .The water strikes the wall 20m away at a height of

A swimmer swims with a speed of 10 m/s at angle of 120^0 from direction of river flow. Find velocity of river flow such that swimmer reach exactly opposite point of bank.
