A farmer moves along the boundary of a square field of side 10 m in 10 sec. What will be the magnitude of displacement of the farmer at the end of 2 minutes 20 seconds from what position?

Text Solution

Verified by Experts

Total =side `xx4`
`=10xx4`
=40 m
Total time taken=40s
Total time taken =140 s
Number of rounds = `140/40=3.5`
Displacement = `10sqrt2`M
