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

$w = \frac{v}{r}$

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

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

$RE = \frac{1}{3} * mv^2$

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

$TE = \frac{1}{2} mv^2$

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

$\frac{RE}{TE} = \frac{2}{3}$
