Question

a particle is moving in a circle of diametre 5m. calculate the distance covered and the displacement when it completes 3 revolution​

Answer 1

Answer:

displacement after 3 revolutions is zero as the point of start and stop are same.

distance covered = 3*2πr

radius= 5/2 m

distance covered= 3*2π*5/2

= 15π m

= 47.14 m (ans)

Answer 2

Answer:

formula of circular motion is 2πs
