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 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 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 river is flowing due east with a speed 3m/s. Swimmer can swim in still water at a speed of 4 m//s If he wants to start from pont A on south bank and reach opposite point B on north bank. Which direction should he swim.

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 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.
