Relative Motion
Boat velocity 4 m/s north, current 3 m/s east. Resultant speed magnitude is:
Select the correct option:
Solution
5 m/s
The boat's resultant velocity vr is the vector sum of its velocity in still water and the river current velocity. Since North and East are perpendicular: vr=vnorth2+veast2 vr=42+32=16+9=25=5 m/s.
