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.

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. In such instances as this, the magnitude of the velocity of the moving object whether it be a plane or a motorboat with respect to the observer on land will not be the same as the speedometer reading of the vehicle. Motion is relative to the observer. The observer on land, often named or misnamed the "stationary observer" would measure the speed to be different than that of the person on the boat. The observed speed of the boat must always be described relative to who the observer is. To illustrate this principle, consider a plane flying amidst a tailwind. A tailwind is merely a wind that approaches the plane from behind, thus increasing its resulting velocity.

If a swimmer standing on South bank of the river wants to swim across the river in the shortest time, then he should swim in a direction speed of swimmer in still water. If a swimmer wishes to cross a river in the shortest path find the direction in which he should swim to achieve this. Let's assume that the swimmer is at point A on one side of the river and wants to reach point B on the other side. Velocity of the river water is 5 m s.
