A swimmer capable of swimming with velocity `v` relative to water jumps in a flowing river having velocity `u`. The man swims a distance `d` down stream and returns back to the original position. Find out the time taken in complete motion.

`t=t_("down") +I_(u p)`
` =(d)/( v+u ) +(d)/( u-v) = (2 du )/(u^2 -v^2)`

A boatman moves his boat with a velocity 'v' (relative to water) in river and finds to his surprise that velocity of river 'u' (with respect to ground) is more than 'v'. He has to reach a point directly opposite to the starting point on another bank by travelling minimum possible distance. Then

A swimmer is capable of swimming at 1.65ms- in still water. If he swims directly across a 180m wide river with water flow at 0.85 ms^(-1) ', how far down stream will he reach? How long will it take to reach the other side ?

The velocity if a swimmer (v) in stil water is less than the velocity of water (u) in a river. Show that the swimmer must aim himself at an angles cos^-1 (v//u) with upstream in order to cross the river along the shortest possible path. Find thr drifting (distance moved along the direction of stream in crossing the river) of the swimmer along this shortest possible path.

A man wants to swim in a river from A to B and back from B to A always following line AB (Fig. 5.94). The distance between points A and B is S . The velocity of the river current v is constant over the entire width of the river. The line AB makes an angle prop with the direction of current. The man moves with velocity u at angle beta to the line AB . The man swim to cover distance AB and back, find the time taken to complete the journey. .
