Question

A man is running in a circle of radius 10m and complete 4 rounds. then his displacement is​

Answer 1

Answer:

zero

Explanation:

as the particle or the man has come to place where he started to move so displacement is zero

hope it helped

Answer 2

Given  :  A man is running in a circle of radius 10 m and completes 4 rounds.

To Find :  his displacement  

Solution:

Displacement is   the distance between initial position and final position

Displacement = Final position - Initial position

Man completes 4 rounds   Hence he is back at initial position.

Final and initial positions are same

Hence Displacement is Zero

Additional Info :

For Distance covered  in 4 rounds = 4 * 2 *  π  * 10  = 80π m
