A ring, a cylinder, and a spherical shell, all made of the same material and of same mass and having the same radius, are made to role without slipping along an inclined linear ramp. Which one of the following statements is necessarily CORRECT? Neglect air resistance.

A). If all objects are let go from rest at the top of the ramp, the spherical shell will reach the bottom first.

B). If they are launched up the ramp with identical initial linear speeds, cylinder will travel farthest up the slope.

C). If they are launched up the ramp with identical initial total kinetic energies, all three objects will travel the same distance before coming to rest momentarily.

D). If all objects are let go from rest at the top of the ramp, the cylinder will have the greatest rotational kinetic energy at the bottom.
