Question

A farmer 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 minutes 20 seconds.​

Answer 1

Answer:

5 m

Explanation:

farmer can walk 10m in 40s

2min 20s = 140s

in first 40s farmer move from A to B

in next 40s move from B to C

next 40s move from C to D

now only 20s are left and in 20s farmer can move from D only 5m

hence displacement is 5m from initial point
