. A cyclist moving along a circular path of radius 63 m completes three rounds in three minute. Calculate (i) The total distance covered by him during this time (ii) Net displacement of the cyclist (iii) The speed of the cyclist

1) Total distance travelled by the cycle is 3×2×π×63=1187.5.
2) Since the cycle coming back to same position the total displacement is zero.
3) Speed of the cycle is v=1187.53×60=6.59 ms-1
