A solid cylinder is released from rest from the top of an inclined plane of inclination $\displaystyle 30^{\circ}$ and length $\displaystyle 60$ cm . If the cylinder rolls without slipping, its speed upon reaching the bottom of the inclined plane is $\displaystyle \_\_\_\_$ $\displaystyle \mathrm{ms}^{-1}$.
(Given $\displaystyle \mathrm{g}=10 \mathrm{~ms}^{-2}$ )
