Question $3$ of $3$

${00}_{\mathrm{.}5}$ A spherical shell of radius $3\mathrm{.}34$ cm and a sphere of radius $7\mathrm{.}97$ cm are rolling without slipping along the same floor. The two

objects have the same mass.

If they are to have the same total kinetic energy, what should

the ratio of the spherical shell's angular speed ${}_{\text{s}\text{h}\text{e}\text{l}\text{l}}$ to the sphere's angular speed ${}_{sph}$ be$?$

$\frac{{}_{\text{s}\text{h}\text{e}\text{l}\text{l}}}{{}_{sph}}=$
