r=10m
t=40sec
as in this time the athlete covers one revolution the initial and the final position is same so the displacement is 0
v=displacement/time
v=0/40
velocity =0
t=40sec
as in this time the athlete covers one revolution the initial and the final position is same so the displacement is 0
v=displacement/time
v=0/40
velocity =0
