A flywheel of mass 4 kg has a radius of gyration of 0.1 m . If it makes 4 revolutions/sec , then its rotational K.E. is ("use "pi^(2)=10)

A fly wheel of mass 60 kg and radius 40 cm is revolving at 300 rpm, then its rotational K.E. is

The ratio of average translational K.E. and average rotational K.E. of a linear polyatomic molecule at temperature T is:

A solid sphere rolls on a table without any slipping. What is the fraction of total K.E. associated with rotational K.E.?

A disc rolls on a table. The ratio of its K.E. of rotation to the total K.E. is -

If rho is the density of its material, then its rotational K.E. is given by

The moment of inertia of a wheel of radius 20 cm is 40 kgm^(2) if a tangential force of 80 N applied on the wheel, its rotational K.E. after 4s is

A body rolls without slipping. The radius of gyration of the body about an axis passing through its centre of mass is K . The radius of the body is R . The ratio of rotational kinetic energy to translational kinetic energy is.
