A solid sphere is rolling without slipping on a horizontal surface. The ratio of its rotational kinetic energy to its translational kinetic energy is

The moment of inertia of a flywheel having kinetic energy 360 J and angular speed of 20 rad s ^-1 is

A body rolls down an inclined plane. If its kinetic energy of rotation is 40% of its kinetic energy of translation, then the body is

A coin is of mass 4.8 kg and radius one metre rolling on a horizontal surface without sliding with angular velocity 600 rotation/min. What is total kinetic energy of the coin ?

A thin metal disc of radius of 0.25 m and mass 2 kg starts from rest and rolls down on an inclined plane. If its rotational kinetic energy is 4 J, at the foot of inclined plane, then the linear velocity at the same point, is in ms ^-1.

A meter stick is held vertically with one end on the floor and is then allowed to fall. Assuming that the end on the floor the stick does not slip, the velocity of the other end when it hits the floor, will be

A disc is rolling on the inclined plane, what is the ratio of its rotational KE to the total KE ?

If the angular momentum of a rotating body about a fixed axis is increased by 10%. Its kinetic energy will be increased by

A solid uniform sphere resting on a rough horizontal plane is given a horizontal impulse directed through its centre so that it starts sliding with an initial velocity v_o . When it finally starts rolling without sliping the speed of its centre is
