Question

A body covered a distance of x meter along a semicircular path. Calculate the
magnitude of displacement of the body, and the ratio of distance to displacement?

Answer 1

Let radius Be (R)
perimeter of semicircle = pie R
given that
x=pie R
R=x/pie
DISPLACEMENT=diameter=2r

2r=2x/pie
Distance:Displacement=x:2x/pie

Answer 2

magnitude of displacement=x m
distance covered =1X
ratio of distance to displacement=πx/x
=π:1
