A sailor steers a boat on a trip with three legs. Find the boat’s total displacement (magnitude and direction) relative to its starting point.
First, the boat moves 5.0 km due west.
Then, it turns around and goes 3.0 km at 25° north of east.
Finally, the boat changes direction again and moves 4.0 km at 30° south of east
1.4 km 30 south of east
