The flywheel of a gasoline engine is required to give up 300 J of kinetic energy while its angular velocity decreases from 600 rev min^(-1) to 540 rev. min^(-1) . What is the moment of inertia of the flywheel ?

The flywheel of a gasoline engine is required to give up 300 J of kinetic energy while its angular velocity decreases from 600 rev min^(-1) to 540 rev. min^(-1) . What is the moment of inertia of the flywheel ?

A fan is making 600 rev/min. If it makes 1200 rev/min, what is the increllse in its angular velocity?

A flywheel in the form of disc is rotating about an axis passing through its center and perpendicular to its plane looses 100J of energy , when slowing down from 60 r.p.m. to 30 r.p.m. Find its moment of inertia about the same axis and change in its angular momentum.
