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 swims from a point A against a current for 5 minutes and then swims backwards in favour of the current for next 5 minutes and comes to the point B. If AB = 100 metres, the speed of the current (in km per hour) is :

A swimmer wishes to reach directly opposite bank of a river, flowing with velocity 8 m/s. The swimmer can swim 10 m/s still water. The width of the river is 480 m. Time taken by him to do so:

Velocity of the river with respect to ground is given by v_0. Width of the river is d. A swimmer swims (with respect to water) perpendicular to the current with acceleration a = 2t (where t is time) starting from rest from the origin O at t= 0. The equation of trajectory of the path followed by the swimmer is

A swimmer wishes to reach directly opposite bank of a river, flowing with velocity 8 m/s. The swimmer can swim 10 m/s still water. The width of the river is 480 m. Time taken by him to do so:

The stream of a river is flowing with a speed of 2 km/hr. A swimmer can swim at speed of 4 km/hr. What should be the direction of the swimmer with respect to the flow of the river to cross the river straight ?
