Question

if a body is moving in circular track of radius 14 m and completes 2.5 rounds. find total distance and displacement covered by it​

Answer 1

Answer:

Explanation:

we know that, distance is the total length of path covered.

now here body is moving in circular path and completed 2.5 rounds.

so, its distance covered = 2.5 x circumference of circular path

                                        = 2.5 x 2 x pi x r

                                        = 2.5 x  2 x 22/7 x 14

                                        = 2.5 x 2 x 22 x 2

                                        = 220 m

Displacement is the shortest distance between finial and initial position.

so at the end of 2.5 rounds the body will be at the another corner of the diameter from where it was started.

             displacement = diameter

                                    = 2 x 14  =  28 m
