Answer:
his displacement is 5m
Explanation:
A is the stage at which a man starts walking. He's walking 4 m north, i.e. AB, then going 3 m east, i.e. BC. The displacement is the connecting straight line between the original and the final position. The displacement is thus the AC hypotenuse of the right-angle triangle. By applying the theorem of hypotenuse, we get
⇒displacement=16+9−−−−−√=25−−√=5m
