A car is going with constant speed on a circular path. If it starts from point A at t = 0 and reaches diametrically opposite point B after 2 sec then find its angular velocity.
In going from A to B the car is displaced by an angle of 180∘.
So, angular displacement = π radians
Time = 2 sec
Angular velocity = angular displacementtime ω=π2radsec
An insect moves along a circular path of radius 10 centimetre with a constant speed. It takes one minute to move from a point on the path to a diametrically opposite point. Find- A. the distance covered. B. The displacement C. The average velocity
