Uniform circular motion describes the motion of a body traversing a circular path at constant speed. Since the body describes circular motion, its distance
from the axis of rotation remains constant at all times. Though the body's
speed is constant, its velocity is not constant.
(1) What is the distance travelled by the object if it goes a complete round in a
circular path of radius 50m?
(II) What is the displacement in the above situation?
(iii) Calculate the speed of the object if it takes 20sec to complete a round.
(iv) Calculate the average speed after completing 3 rounds.
PLEASE HELP
