Question

A farmer moves along the Boundry of a Square Field of 10 meter in 40 seconds what will be the magnitude of displacement of the farmer at end of two minutes 20 seconds from his initial position

Answer 1

Answer:if farmer covers 10 m in 40 sec so , in 2m20s he can cover

30+5=35 meters and its displacement will be 0 .

Explanation: if he covers 10 m in 40 sec

                     converting 2m20s in sec

                    after converting it will be 140sec

                    10 m =40sec ,  x m = 140 sec

                     x/10 =140/40

                      x=140*10/40

                      x = 35
