A swimmer crosses a river in shortest distance

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 flowing stream of width d to and fro normal to the flow of the river at time t 1. It will take time for the swimmer to cover the 2d distance in still water. If the time taken against the stream to cover a certain distance is three times as compared to the time taken along the stream, then what is the speed kilometer per hour of the stream? A swimmer takes 4 second in crossing some distance in downstream and taken 6 second in upstream for same distance then find the time taken by him to cover same distance in still water. What is the ratio of the time taken to swim across in the shortest time to that in swimming across over shortest distance. To cross the river in shortest distance, a swimmer should swimming an angle theta with the upsteram. Differentiate between plant and animal cell. Highlight the state and non-state initiatives addressing caste and tri

Keeping the direction fixed the swimmer crosses the river in 15 sec.

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. As such, there is no way that the current is capable of assisting a boat in crossing a river. If we have the velocity of the boat and the velocity of the river, then we can find the angle for which drift is minimum for that particular velocity of boat using the above relation.

On occasion objects move within a medium that is moving with respect to an observer. For example, an airplane usually encounters a wind - air that is moving with respect to an observer on the ground below. As another example, a motorboat in a river is moving amidst a river current - water that is moving with respect to an observer on dry land.
