Question

A farmar move along the boundary of a square field of side 8m in 32 s. What will be the magnitude of the displacement of the farmar at the end of 1 min 20 sec.

Answer 1

Farmer takes 40 s to move along the boundary.

Thus, after 3.5 round farmer will at point C of the field.

Thus, after 2 min 20 seconds the displacement of farmer will be equal to 14.14 m north east from initial position. 3.
