Question

13. A car takes 20 s to move around about of radius 14 m calculate average speed and average

velocit​

Answer 1

Answer:

Average speed = 4.4m/s

Average velocity = 0

Explanation : average velocity is displacement/time , in a circular path displacement is zero since you reach the same point in which you started .

Average speed = distance/time

In a circular path distance is 2πR

Distance = 2*22/7*14 = 88

Time (given) = 20 secs

Average speed = 88/20 = 4.4m/s
