Question

o
A car runs at constant speed on a circular track of
radius 100 m taking 62.8 s on each lap. What is the
average speed and average velocity on each complete
Tap?
(A) velocity 10 m/s speed 10 m/s
(B) velocity zero, speed 10 m/s
(C) velocity zero, speed zero
(D) velocity 10 m/s, speed zero​

Answer 1

Answer:

Explanation:

After each circular lap,the car reaches its initial position,therefore displacement is 0.This implies average velocity=total displacement/total time= 0. Average speed =total distance/total time =2*3.14*r/62.8 = 10

Hence, Option B is correct..........
