A man can swim at the rate of `5 km//h` in still water. A river `1 km ` wide flows at the rate of `3km h^(-1)`. A swimmer wishes to cross the river straight.

A man can swim at the rate of 5 km//h in still water. A river 1 km wide flows at the rate of 3km h^(-1) . A swimmer wishes to swim across the river directly opposite to the starting point. (a) Along what direction must the man swim ? (b) What should be his resultant velocity ? ( c) How much time will he take to cross the river ?

A man wishes to swim across a river 0.5km. wide if he can swim at the rate of 2 km/h. in still water and the river flows at the rate of 1km/h. The angle (w.r.t. the flow of the river) along which he should swin so as to reach a point exactly oppposite his starting point, should be:-
