A swimmer capable of swimming with velocity `v` relative to water jumps in a flowing friver having velocity `u`. The man swims a distance `d` down stream and returns back to the priginal position. Find out the time taken in complete motion.

Text Solution

Verified by Experts

Tatal time =Time of swinning downstream +Time of swinming upstream
Velocity of the man during swimming downstream`=v+u`
Velovity ot the man during swimming sustream`=v-u`
`t=t_(down)+t_(up)=t_(down)+t_(up)=(d)/(u)+(d)/(v-u)(2dv)/(v^(2)-u j^(2)`.

A man can swim with velocity v relative to water. He has to cross a river of width d flowing with a velocity u (u gt v) . The distance through which he is carried down stream by the river is x. Which of the following statements is correct?

A man can swim with velocity v relative to water. He has to cross a river of width d flowing with a velocity u(u gt v). The distance traveled by man along the flow is x, when he reaches to opposite bank. For x to be minimum the person should swim at an angle alpha with the direction of the flow of water, where alpha is

A swimmer can swim with velocity of 12 km/h in still water. Water flowing in a river has velocity 6 km/h.
