Question

A body is moving around a circular path with radius r. Find the distance and displacement after two and a half revolutions.

Answer 1

distance after two revolutions = 4πr
distance after half revolution =πr

displacement after two revolution = 0
displacement after half revolution = 2r

hope this helps!!!!!!!!!

Answer 2

for distance=
$2\pi(r) + 2\pi(r) + \pi(r)$
$5r\pi$
displacement=2r
