A swimmer crosses a flowing stream of width. The time taken to cover the same distance up and down the stream is t 2. If t 3 is the time the swimmer would take to swim a distance 2d in still water, then n. A swimmer crosses a flowing stream of width d toand from in time t 1. Then the time the swimmer would take to swim a distnace 2d in still water is.

A swimmer crosses a river in shortest distance

A man swimming downstream overcomes a float at a point M. Then the ratio of speed of swimmer with respect to still water to the speed of the river will be. Swimmer takes 6 seconds to cross the river of width 60 m. The velocity of the swimmer with respect to water will be :. To cross the river in shortest distance, a swimmer should swimming an angle theta with the upsteram. What is the ratio of the time taken to swim across in the shortest time to that in swimming across over shortest distance. Velocity of the river water is 5 m s. Swimmer takes 12 seconds to cross the river of width 60 m. The velocity of the swimmer with respect to water will be:. A swimmer start swimming from a sea shore in south direction and other one in east direction. Their distance becomes km. The speed of a swimmer with respect to the water is v, the speed of the stream is u. In what direction should the swimmer move to reach the opposite point on the other bank of the river? How long will he swim if the width of the river is l?

Home » Physics » Problem » What condition is satisfied if the swimmer desires to swim minimum distance to cross the river? When he crosses a river with shortest time one component of boat velocity is opposite to velocity of water and other component is perpendicular to velocity of water. Therefore if the reverberation time becomes too large it produces an echo. So option 2 is correct. The boat cannot cross the river to an exactly opposite point. Factors that affect the speed of a river include the slope gradient, the roughness of the channel, and tides. Rivers tend to flow from a higher elevation to a lower elevation. The river moves downstream parallel to the banks of the river.
