Question

AB is a diameter of a circle of radius r. A particle starting from A completes two and a half revolution. Calculate the distance travelled by the particle and its displacement. *
5 ∏ r, r
2 ∏r, 2r
5∏r, 2r
5r, 2r​

Answer 1

Answer:

distance 5π r and displacement 2r

Answer 2

Explanation:

distance travelled 2whole1/2round

therefore distance = .

$5\pi \: r$

displacement =2r
