Question

A body is moving on a circular path with a constant speed of
Ilms' and completes full circle in 5 seconds. Calculate its
distance and displacement in half round.​

Answer 1

Explanation:

According to your question, the body moves from point A to point B thereby completing half a revolution. Since distance is the length of path covered therefore it will be equal to half the circumference i.e. 1/2 × 2pi r or pi × r. And the displacement is equal to the distance between initial and final point. Therefore it will be equal to the diameter or r+r=2r.
