A spherical shell rolls without sliding along the floor. The ratio of its rotational kinetic energy (about an axis through its c
True [87]

Answer:

The ratio  is  \frac{RE}{TE}  = \frac{2}{3}

Explanation:

Generally  the Moment of inertia of a spherical object (shell) is mathematically represented as

              I  =  \frac{2}{3} *  m r^2

Where m is  the mass of the spherical object

       and   r is the radius  

Now the the rotational kinetic energy can be mathematically represented as

       RE  = \frac{1}{2}*  I *   w^2

Where  w is the angular velocity which is mathematically represented as

             w =   \frac{v}{r}

=>           w^2  =   [\frac{v}{r}] ^2

So

             RE  = \frac{1}{2}*  [\frac{2}{3} *mr^2] *   [\frac{v}{r} ]^2

            RE  = \frac{1}{3} * mv^2

Generally the transnational  kinetic energy of this motion is  mathematically represented as

                TE = \frac{1}{2} mv^2

So  

      \frac{RE}{TE}  =  \frac{\frac{1}{3}  * mv^2}{\frac{1}{2} * m*v^2}

       \frac{RE}{TE}  = \frac{2}{3}
