A duck with a still water velocity of 5.00 km/hr heads across a stream that flows directly West with a velocity of 3.00 km/hr. a) What must be the heading of the duck if it is to maintain a path directly South across the stream ? Draw a vector diagram along with your work. b) How long will it take the duck to cross the stream if the stream is 200.m wide and the duck maintains its heading ? (c) What will be the duck’s resultant velocity if it does not fight the current ? Draw a vector diagram along with your work. ) d) How long will it take the duck to reach the opposite side if it does not fight the current ? Remember, the stream is 200.m wide. e) How far downstream, relative to the bank, will the duck be carried if it does not fight the current ?
