Question

a person Travels on a circular track of radius 14 metre calculate the distance travelled and the displacement of person in one round of journey​

Answer 1

Answer:

radius of the circular track=14m

since the person moves around the circular track once , the distance covered by him will be equal to the circumference of the track;

Thus, distance covered = 2πr

= 2×22/7×14

88m

since the person after makin one full round returns back to his starting position;

displacement= 0

Answer 2

Answer: 2πr and 0 respectively

Explanation: distance travelled will be equal to the length of circumstances of the circle having radius r which is equal to 2πr.

Displacement it the straight line distance between initial and final point of the journey. Since here initial and final points are same total displacement will be equal to 0
