Question

Farmer starts moving along the sides
of a rectangular field. Find the
displacement in given figure if farmer
starts from A and stop at C.If CB=5m ,AB=12m,DC=12m,DA=5m.​

Answer 1

Explanation:

Hi friend,

Total distance covered 10m in 40sec

Total time taken= 2min 20sec= 140sec

Total round completed = 140/40=3.5 rounds

So If an object moves from A to D, the shortest path will be from A to C. So displacement is AC, that we will find by phythogoras theorem.

AC2= AB2 +BC2 

AC2= (10)2 +(10)2

AC2= 100+100

AC2=200

AC = (200)1/2

 

AC= 10× (2) ½ 

Hope it helps......
