46 squared + 23 squared = the resultant displacement squared.

Compass degrees measure clockwise, starting at North is 0°
south
The total displacement is 30 meters South. Displacement is the difference between the initial and final positions of an object, irrespective of the path taken. In this case, the person returns partially to the initial position after moving North by 50 meters.

find the resultant of the following displacement a=20km 30south of east
The resultant is 220 ms North (1450 - 1230 = 220). It is the net displacement when adding the two displacements in opposite directions.
100 km and 75 km are displacements, NOT velocities. The resultant displacement is 25 km north,
The resultant is 2 km South.
6.3 meter
If a person walks 10 meters north and then walks 10 meters south, their total displacement would be zero since they would end up back where they started.
the east /west distances are the same but the north south are different. so subtract the north from the south distances and you end up with 60 meters south.
