d=50m
r= 50/2=25m
t=10 sec
Circumference of the circular path = 2πr
=2π(25)= 157m
distance covered in 10sec = 157m
distance covered in 1 sec = 157/10= 15.7m
Distance covered in 45 sec = 15.7x45=706.5m
Displacement.
After 45 sec he will reach the opposite direction of the path from where he started. So his displacement will be 50m
