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