Question

A player moves along the boundary of a square ground of side 50 m in 200 sec.The magnitude of displacement of the farmer at the end of 11 minutes 40 seconds from his initial position is


​

Answer 1

Answer:

11 min 40 sec=700 s

in 200 sec 4×50 m (boundary=perimeter)=200m

so in 700 s he move 700 m

so he make 3 and 1/2 rounds

the displacement will be the length of diagonal as he will be at opp vertex which will be by Pythagoras
