Work Step by Step
The correct answer is: (c) north of east The boy's resultant velocity vector will be the sum of the the water's velocity vector and the velocity vector of the boat. Since the water's velocity vector is 1 m/s south, the boy needs to paddle so the north component of the boat's velocity vector is 1 m/s north. To go straight east across the river, the boy should head north of east.
