A cord is wrapped around the rim of a solid cylinder of radius 0.25 m and a constant force of 40 N is exerted on the cord. The cylinder is mounted on frictionless bearings and its moment of inertia is $4kg-m^2$ The angular velocity of the cylinder after 5 m of cord has been unwound, is ${\omega }_1$. If the 40 N force is replaced by a 40 N weight and released from rest at the top, the angular velocity of the cylinder after 5 m of cord has been unwounded is ${\omega }_2$ (Given, $\mathrm{g}=10{\mathrm{ms}}^{-2}$ ). Then
