a boy covers half of a circular track of radius 14m in 10s. find the ratio between average velocity and average speed
Answers
Answer:
The average velocity is defined by the ratio of displacement to time. Since, after one complete lap the car returns to it's original position

Please marked me as Brainlyst answer please please.......
Answer:
The ratio between average velocity and average speed is 0.
Explanation:
Total distance 14 m
Total time taken = 10sec
Average speed :
It is the ration of distance upon time
average speed = 14/10
average speed =1.4m/sec
The change in position or (∆x) displacement is divided by the (∆t) time intervals is known as Average displacement.Average velocity is a vector quantity that can be positive or negative depending upon the sign of the displacement.Meters per second (m/s or ms-1) is the S.I unit of average velocity.
average velocity = displacement / time
as the displacement = 0
therefore average velocity = 0
so the ratio of average velocity and average speed = 0/1.4
=0
the ratio between average velocity and average speed is 0.
