Problem

A solid sphere of mass

2.0\,\text{kg}

and radius

0.20\,\text{m}

rolls without slipping along a horizontal surface at a speed of

3.0\,\text{m\,/\,s}

. The moment of inertia of a solid sphere about its center is

I=\tfrac{2}{5}MR^{2}

. Calculate the total kinetic energy of the sphere.
