Answer: Is distance that part covered by the body between its initial and final position
The distance covered will be equal to the circumference of the circle
Distance=2πr=42π=131.8m
Displacement is the shortest distance travelled between the initial and final position
As the initial and final position of the body is the same
Net displacement is zero
Average velocity is the ratio of net displacement covered with respect to time
as NET displacement is zero average velocity of the object is also zero
average speed is the ratio of Total distance covered with respect to time
Time =2 min=2×60=120 sec
Avg speed
= Total distance /time
= 42π / 2 × 60
= 131.8/120
=1.09 m
