What is the angular displacement made by a particle after `5s`, when it starts from rest with an angular acceleration `0.2` and `s^(-2)` ?

A particle is in circular motion with an acceleration alpha=0.2rads^(-2) . (a) What is the angular displacement made by the particle after 5 s? (b) What is the angular velocity at 15 s?. Assume the initial angular velocity is zero.

The angular displacement of a particle is given by theta = t^3 + 2t +1 , where t is time in seconds. Its angular acceleration at t=2s is

An object of mass m has angular acceleration alpha =0.2" rad s"^(-2) . What is the angular displacement covered by the object after 3 second ? (Assume that the object started with angle zero with angular velocity).

A grindstone Is found to have a angular speed of 150 rpm, 10s after starting from rest. The angular acceleration of the grindstone is

The angular displacement of a particle is given by theta =t^3 + t^2 + t +1 then,the angular acceleration of the particle at t=2 sec is ……. rad s^(-2)

the angular velocity omega of a particle varies with time t as omega = 5t^2 + 25 rad/s . the angular acceleration of the particle at t=1 s is
