Question

A body is traveling along a circular path of radius 10 m as shown below. If it travels from A to B, find the distance and displacement of the body.​

Answer 1

The displacement and distance covered by the body are 31.4 m and 20 m repectively.

Explanation:

We are given that:

The radius of the circular path 'r' = 10 m

To find:

The distance and displacement of the body =?

π  = 3.14

Solution:

S =  π r

S = 3.14 x 10 = 31.4 m  

Now the total displacement of the body D =?

R = 10 m

D = 2 x R

D = 2 x 10 = 20 m
