Question

An ant walks 15 m east, then 40 m north, and finally 20 m west. What is the total displacement from the starting point

Answer 1

Answer: 40.311 m

Step-by-step explanation:

Given

Ant walks 15 m east

then 40 m North and finally 20 m west

from the figure, ant is 40 m North and 5 m west

Using Pythagoras, we can write

`\Rightarrow d=√(40^2+5^2)\\\Rightarrow d=√(1625)=40.311\ m`
