Question

A body travels along a circular path of radius 70m. After travelling half a revolution in 20s, find the
displacement of the body​

Answer 1

Answer:

140m

Explanation:

apart from physics,we can solve that mathematically,

if a body travelled in a circular path and completed half a revolution,then the displacement of the body will be the shortest distance between the two points,i.e,diameter of circle=2r=140m.

and if you want the distance covered by the body,then it is half of the perimeter of the circle,i.e,πr=70πm
