A person aiming to reach exactly opposite point on the bank of river is swimming at speed of `6(km)/h` at an angle of `150^(@)` with the direction of flow of water. The speed of water in 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

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, 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 crosses the river in shortest time and reaches at an angle theta= 60^(@) to the direction of flow of water. If the speed of water is v_w = 4 km//hr , find the speed of the man:

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 2 km, the time taken to cross the river is (in hours)

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 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 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 man wants to reach point B on the opposite bank of a river flowing at a speed u as shown in (Fig. 5.193). What minimum speed relative to water to water should the man have so that he can reach directly to point B ? In which direction should he swim ? .
