Question

A man travels a distance of 1.5 m towards East,then 2.0 m towards South and finally 4.5 m towards East.
i).what is the total distance traveled?
ii).what is his resultant displacement?

Answer 1

1Distance moved east=1.5 m+4.5 m=6 m
Distance moved south=2m
By pythagoras theorem,
Displacement=rootover((6m)*(6m)+(2m)*(2m)
=rootover(36m2+4m2)=rootover 40m2=6.32m(approx)
In the 2nd question,the distance is not defined,so 
we can give answers only with variables,which will be answered by someone else.
