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 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 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)

If you are on the west bank of a river that is flowing north with a speed 4m/s. Your swimming speed relative to the water is 5 m/s, and the river is 60m wide. What is your path relative to earth that allows you to cross the river in the shortest time? Explain your reasoning.

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 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 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 ?
