Motion With Constant Angular Acceleration

A particle starts moving with a constant angular acceleration in a circular path. The time at which the magnitudes of tangential and radial acceleration are equal is

A flywheel at rest is to reach an angular velocity of 24 rad/s in 8 second with constant angular acceleration. The total angle turned through during this interval is

A point mass moves along a circle of radius R with a constant angular acceleration alpha . How much time is needed after motion begins for the radial acceleration of the point mass to be equal to its tangential acceleration ?

A circular disc is rotating about its own axis at constant angular acceleration. If its angular velocity increases from 210 rpm to 420 rpm during 21 rotations then the angular acceleration of disc is

Projectile motion is a two dimensional motion with constant acceleration. Is this statement true or false?

A particle is moving in circular path with constant acceleration. In time t after the beginning of motion the direction of net acceleration is at 30^(@) to the radius vector at that instant. The angular acceleration of the particle at that time t is

A body is rotating with 900 rpm. The angular velocity mereates to 2460 rpm in 26secs due to a constant angular acceleration. Total number of revolutions during acceleration is

which of the following equation is incorrect for a body undergoing rotational motion with uniform angular acceleration ( symbols have their usual meanings)

Assertion : Velocity and acceleration of a particle are given as, v=hati-hatj and a=-2 hati+2 hatj This is a two dimensional motion with constant acceleration. Reason : Velocity and acceleration are two constant vectors.
