Question

A solid sphere and a solid cylinder, both uniform and of the same mass and radius, roll without slipping at the same forward speed. It is correct to say that the total kinetic energy of the solid sphere is

less than the total kinetic energy of the cylinder

Answer 1

It is correct to say that the total kinetic energy of the solid sphere is

less than the total kinetic energy of the cylinder

Step-by-step explanation:

The correct option is ; answer is Option ( A ) - is less than the total kinetic energy of the cylinder because moment of inertia of solid cylinder ( 0.5 mr² ) is higher than moment of inertia of sphere ( 0.4 mr² ), as such, total energy of sphere will be less than the solid cylinder.
