A swimmer can swim with speed 12 m/s in still water. Speed of river is 6 m/s. Find angle at which he should swim with downstream so that he reaches directly opposite point on other side

A man can swim at a speed 2ms^(-1) in still water. He starts swimming in a river at an angle 150^(@) with direction of flow of water and reaches at the exactly oppsite point on the opposite bank. (a) Find the speed of flowing water. (b) If width of river is 1 km then calculate the time taken also

A man can swim in still water at 4m//s river is flowing at 2m//s . the angle with downstream at which he should swim to cross the river minimum drift is

A swimmer swims with a speed of 10 m/s at angle of 120^0 from direction of river flow. Find velocity of river flow such that swimmer reach exactly opposite point of bank.

A swimmer wishes to reach directly opposite point on the other bank of a river,flowing with velocity 4sqrt(2)m/s .The swimmer can swim with 8m/s in still water.The angle with the flow direction he should swim to reach the directly opposite point is (A) 45^(0) (B) 90^(0) (C) 135^(0) (D) 150^(0)

A man wishes to cross a river of width 120 m by a motorboat. His rowing speed in still water is 3 m//s and his maximum walking speed is 1m//s . The river flows with velocity of 4 m//s . (a) Find the path which he should take to get to the point directly opposite to his starting point in the shortest time. (b) Also, find the time which he takes to reach his destination.

If speed of water in river is 4 m/s and speed of swimmer with respect to water is 3 m/s, then in which direction the swimmer must swim so that he will reach directly opposite end?

A river flows with a speed more than the maximum speed with which a person can swim in still water. He intends to cross the river by the shortest possible path (i.e., he wants to reach the point on the opposite bank which directly opposite to the starting point). Which of the following is correct ?

A swimmer can swim with velocity of 12 km/h in still water. Water flowing in a river has velocity 6 km/h. The direction with respect to the direction of flow of river water he should swim in order to reach the point on the other bank just opposite to his starting point is.
