Question

A boy completes one round of a circular track of radius R in 40 seconds, its displacement at the end of 2 minute 20 seconds will be?

Please answer with full steps.

Answer 1

Hi friend

Its displacement will be zero because the man completed the cycle.he comes to his original position.

So displacement becomes zero.

Hope this helped you a little!!!

Answer 2

Hey there,

Time in 1 rotation=40 seconds

Total time=140

Number of rotations=140/40=3.5

So he will have way across the original point diametrically. So the displacement is equal to the diameter=2R

PLEASE MARK AS BRAINLIEST IF HELPFUL!!!
