CROSSING RIVER IN MINIMUM TIME

CROSSING RIVER IN SHORTEST PATH (MINIMUM DRIFT)

RIVER-MAN PROBLEM IN TWO DIMENSION ( CROSSING RIVER)

Assertion: To cross the river in minimum time swimmer should swimming in perpendicular direction to the water current. Reason: In this case river flow helps to cross this river.

STATEMENT-1: A man can cross river of width d in minimum time t . On increasing river velocity, minimum time to cross the river by man will remain unchanged. STATEMENT-2: Velocity of river is perpendicular to width of river. So time to cross the river is independent of velcoity of river.

STATEMENT-1: A man can cross river of width d in minimum time t . On increasing river velocity, minimum time to cross the river by man will remain uncharged. STATEMENT-2: Velocity of river is perpendicular to width of river. So time to cross the river is independent of velcoity of river.

In the previous problem, the man wants to cross the river in the minimum time. In which directions, he should move? Find the minimum time to cross the river and his displacement (drift) along the flow.
