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

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