Question

A farmer moves along the boundary of a square field of side 10 m in 40 sec. What will be the magnitude of displacement of the farmer at the end of 2 min 20 sec from its initial position ?

Answer 1

Here is your answer please mark me as brainly.

Answer 2

given:-

perimeter of a square= 10×4= 40

time taken= 40 secs

to find= displacement= ?end of 2mins 20 secs= 140 secs

x=140×40÷40= 140m

Therefore, 140m is the distance covered.

140÷40= 3.5= 3 and 1/2 rounds taken

√10²+10²=14.14m

Therefore, 14.14m is the diagonal.
