Q 2. A farmer moves along the boundary of a square field of side 10 m in 40 s. What will be the magnitude of displacement of the farmer at the end of 2 minutes 20 seconds from his initial position?
Side of the square field =
Perimeter of the square =
According to question,
He completes 1 round in .
Speed of the farmer =
Distance covered in =
Number of round trips completed travelling =
We know, in 3 round trips the displacement will be zero.
In round, the farmer will reach diametrically opposite to his initial position.
