A man in a boat wants to cross a stream 10m wide. Velocity of the stream is √3 m/s and the man can row his boat with a speed of 2 m/s with respect to still water. i) At what angle to the bank should the man row his boat so that he crosses the stream by travelling least possible distance with respect to the bank? ii) Calculate the time of crossing in the above case. iii) If this time is not minimum, find the minimum time. iv) Assume the velocity of the man and the stream to be exchanged. Now, how should the man row his boat so that he lands at a point nearest to the point on other bank which is opposite to the starting point? v) In the situation given above with exchanged velocities, what is the minimum time of crossing?
