Question

before rolling smooth circle liner kinetic of total energy %__________is

Answer 1

Will it has two forms of kinetic energy and that is translational energy moving in a line and there is rotational energy.

The translational energy will be 1/2 m v^2, where v is the linear velocity of the center of the cylinder.

and the rotational energy will be 1/2 m r w^2, where w is the angular velocity in radians per second.

You have to calculate both and sum them together.
