Question

A girl moves along thr boundary of the square field of side 20m in 80 sec .what will be the magnitude of displacement at the end of 200 sec ?Also cakculate average velocity?

Answer 1

magnitude of displacement=0.
hence average velocity =s/t=0/200=0

Answer 2

when the girl move 200m the final position of is initial position so displacement is 0.
displacement is 0 so, average velocity is also 0. THANKS
