a body covers a circular path of radius 'R' in 20 seconds.calculate the distance and displacement of the body at the end of 70 seconds.
It will have made 70/20 = 3.5 trips around the circular track.
The displacement from the original location will be 2R.
The distance traveled will be
3.5 * 2 pi R = 7 pi R.
