Answer 2

Answer:

Explanation:

Consider r as the radius of semicircular path.  

When a body covers distance of x meter along a circular path, distance covered by body will be 2π r. But here body is covering distance along semicircular path. So distance covered by body will be π r.

Now Let’s find the displacement of the body.

Distance covered by body, A = π r   ------(1)

Displacement = Diameter of the semicircular path = 2r ----- (2)

Putting the value of r from equation (1) to equation (2),  

Displacement = 2 [A/ π]
