Not sufficient!

A uniform solid sphere of mass $m$ is released from top of a fixed incline plane of inclination $\theta$ .If coefficient of friction between the incline and sphere is $half$ the minimum value required for pure rolling of the sphere,then find the kinetic energy of sphere after moving a distance $l$ on the incline plane.

$NOTE$ :

$l$ is measured from the point of release of sphere along the incline.

Use values:

$\theta$ = $\sin ^{ -1 }{ \frac { 6 }{ 11 } }$

$m$ = $2$ Kg

$l$ = $1$ m

$g$ = $10m{ s }^{ -2 }$
