A uniform sphere of mass 500 g rolls without slipping on a plane horizontal surface with its centre moving at a speed of $5.00\,\mathrm{cm\,s^{-1}}$. Its kinetic energy is:\\
(1) $8.75 \times 10^{-4}\,\mathrm{J}$\\
(2) $8.75 \times 10^{-3}\,\mathrm{J}$\\
(3) $6.25 \times 10^{-4}\,\mathrm{J}$\\
(4) $1.13 \times 10^{-3}\,\mathrm{J}$
