Question

a car runs at a constant speed of circular track of radius 200 m taking 62.8 second on each lap. find the average velocity and average speed on each Labs

Answer 1

Hey mate

average speed means total distance covered by particle per interval of time .
e.g
average speed =total distance/total time
= 2π(200)/62.8
=2 × 314 /62.8 =10 m/s

average velocity = total displacement covered per unit time

e.g
average velocity= displacement/time
but we know if any particle moves in circular path and complete the revolution then, displacement is equal to zero.

now,
average velocity =0/ 62.8 =0
