The frequency of a particle performing circular motion changes from 60 rpm to 180 rpm in 20 s . Then the angular acceleration is

Attempt any SIX : The frequency of revolution of a particle performing circular motion changes from 60 r.p.m to 180 r.p.m in 20 seconds. Calculate the angular acceleration of the particle.

The speed of the wheel of an engine changes from 600 rpm to 1200 rpm in 5 s. Then its angular acceleration in rad//s^(2)

Theangular speed of a car increases from 600 rpm to 1200 rpm in 10 s .What is the angular acceleration of the car ?

When the angular velocity of a particle performing circular motion is decreasing in anticlock wise direction then the direction of angular acceleration will be

For a particle performing a uniform circular motion the acceleration is
