Question

Arun moves 3 kilometre towards north and then takes a turn and moves 4 kilometre towards east calculate the distance and displacement of Arun​

Answer 1

answer:

distance= 7 km and displacement= 5km

Explanation:

given ,

displacement=v

distance covered by arun towards North (x)=3 km

distance covered by arun towards east(y) =4 km

.: total distance covered by arun = x+y= 3+4=7 km

and, by using Pythagoras theorem we can find v,

:. x² + y²= v²

3²+4²=v²

9+16= v²

25=v²

5= v

:. displacement=5 km

hope it helps
