Hola!
Given,
Radius = 140m
Time = 20 sec.
Total distance = circumference of the circle = 2πr = 2(22/7)(140)m = 880m
We know,
Speed = Total distance/time
=> Speed = 880m/20s
=> Speed = 4m/s
Thus,
The speed is 4m/s
Since the car is moving in a circular path where it completes one round, the initial and final points lie at the same points i.e., they co-incide each other.
Thus,
The displacement is 0
Peace out ✌️
