5) There are two boats in the water. Boat 'A' is traveling at 10m/s North. Boat 'B' is traveling at 12m/'s East. Both boats are in the same river, which is flowing at 2m/s South. A man in boat ' A' is walking to the left side of the boat at 1m/s. A woman in boat 'B' is walking to the right side of the boat at 1.4m/s. Determine the velocity (magnitude & direction) of the woman w.r.t the man
