Question

A cycle moving on a circular track of radius 40m completes half a revolution in 4 sec. What is the average velocity of motion

Answer 1

Radius = 40m
Diameter = 80m


After completing half revolution the cycle will be at the distance equal to diameter of circle from where it started its journey.

Therefore, Velocity = displacement/ time
= 80/4
= 20m/s

Answer 2

Hi friend,

Here is your answer,
______________________________________________________________

Radius =40m

Diameter = 80m

Displacement = diameter = 80m
Time = 4 seconds

Speed = 80
                4

           = 20m/s
