Question

A boy complete one round of a circular track of radious 20m in 50second the displacement at the end of 4minute 10second will be?

Answer 1

Hi Mate!!!

4 min 10 sec = 250sec

50 sec = 1 round


1 sec = 1 / 50 round


250 sec = 250 / 50. round.

250 sec = 5 ROUND.


For each round the displacement is zero because intial and final position coincide.


So,. Displacement after 250 sec = 0


Have a great future ahead
