Question

2. A person walks along the sides of a square field. Each side is 100 m long. What is the maximum magnitude of displacement of the person in any time interval?​

Answer 1

Explanation:

The maximum displacement is the diagonal of the square field .

$side \: of \: square = 100 \: m$

$diagonal = \sqrt{100 {}^{2} } + \sqrt{100 {}^{2} } =$

$= \sqrt{20000 = 100 \sqrt{2 \: m} }$

$= 141.2m$

So, maximum displacement is 141.2m
