[M⁰L ⁰T^--2] represents dimensional formula for

The dimensional representation of angular velocity is identical to that of

A flywheel rotating about a fixed axis has a kinetic energy of 360 J when its angular speed is 30rad/s. The moment of inertia of the wheel about the axis of rotation is

The moment of intertia of a ring of mass M and radius R about an axis passing through the centre and perpendicular to its plane is 

The angular speed of a body is expressed in 

A thin, uniform circular ring is rolling down an inclined plane of inclination 30º without slipping.Its linear acceleration along the inclined plane will be

The dimensional representation of angular acceleration is

At any instant, a rolling body may be considered to be in pure rotation about an axis through the point of contact. This axis is translating forward with speed

If two particles have masses m₁ and  m₂, then the reduced mass is given by

A wheel of moment of inertia 5× 10-3 kg m2 is making 20 revolutions per second. It is stopped in 20 seconds, then the angular retardation is
