Question

A particle is moving in a circle of radius 5 metre calculate the distance and displacement after 3.5 rounds???

Answer 1

distance 109.9
displacement 10

Answer 2

distance
$= 2 \times \pi \times r$/time
$2 \times 22 \div 7 \times 5$/
$= 44 \times 5 \div 7$
$109.9\: meter$
displacement =diameter of the circle
=2r
$2 \times 5 = 10meter$
