Rolling sphere :-

A sphere of radius R is projected up an inclined plane of angle \(\theta\) with initial speed u and angular velocity \({ \omega }_{ 0 }\) in the direction such that it will roll up. The coefficient of friction is \(tan(\theta )/7\) and it is given that u> \({ \omega }_{ 0 }\) . Give the direction of friction for different parts of motion as sphere rises. Obtain the time for which sphere moves up the plane till it stops.
