Answer» r moves ALONG the boundary of a square field of side 10M in 40s.______________________What will be the magnitude of displacement of the farmer at the end of 2 min 20s. Find its INITIAL position.______________________________________________First,Side of square = 10mPerimeter of square = 4 × side = 4 × 10 = 40mTime taken = 40s2 min 20 s in seconds = 140sThan,Shortest path is A to C .So,we will find it using Pythagoras theorem :_______________________ |
