A man wants to reach point B on the opposite bank of a river flowing at a speed 4m/s as shown in the fig `1E.125` (a) what minimum speed relative to water should the man have so that he can reach point B directly by swimming? In which direction should he swin?

A man wants to reach point B on the opposite bank of a river flowing at a speed 4m//s as shown in the figure. What minimum speed relative to water should the man have so that he can reach point B directly by swimming?

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

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 ? .

A man in a row boat must get from point A to point B on the opposite bank of the river (see figure).The distance BC=a .The width of the river AC=b .At what minimum speed u relative to the still water should the boat travel to reach the point B ?The velocity of flow of the river is v_(0)

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 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 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 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 man can swin with speed 6 km/h in still water. If he tries of swim across a river flowing with speed 5km/h, how fast does a leaf floating on water appears to go , to the man ?
