Question

athlete completes 3.5 round of a circular track compare his displacement with distance covered​

Answer 1

Answer:

Distance = 7 pie r

Displacement = pie r

Explanation:

Because displacement is the shortest path covered

Answer 2

Answer:

displacement=1/2*2*22/7*r

distance =3.5*2*22/7*r

Explanation:

displacement is not zero because it completes three complete and half a round therefore displacement of 3 round is zero but the remaining half=1/2*2*22/7*r

circumference of circle=2*22/7*r

as it cover 3.5 round so its distance=3.5*2*22/7*r
