Question

A farmer is moving along the boundary of asquare field of side 20m in 80s.what will be the magnitude of displacement at the end of 200s. Find the average velocity of the farmer

Answer 1

in 200s he will cover 50m and sice its a square he will end at 20 m east and 10 m north from starting point.
disp = sqrt(500)
and avg vel = disp/200
