hi!
here is a problem for which I cannot really feel the answer though I know the answer
here it is
A boat can travel at a speed of 3m/s on still water.A boatman wants to croo a river whilst covering the SHORTEST POSSIBLE DISTANCE.in what direction should he row w.r.t the river bank if the speed of the water is 4 m/s
the solution to this problem was given in an orientation class and the main step is that the resultant velocity must be perpendicular to the velocity of man in still water
Plz explain me why is it so...
thanks in advance...
