Question

find the ratio of distance and displacement when a car completes 3.5 rounds of circular track of radius 100m

Answer 1

its distance is 3.5*(2πr).
=7πr metre
=700π m

its displacement is distance of final positions and initial position.
ie. 2r=2*100=200m.
so ratio=700π/200=3.5π

Answer 2

Answer:

11:1

Explanation:

r=100m

2πr=44/7 x 100 = 4400/7

distance= 4400/7 x 35/10 = 2200m

displacement = πr = 200m

2200:200 = 11:1
