Vedclass · Answer

(D) When the sphere is thrown up the incline,it has both translational velocity $v$ and angular velocity $\omega$. For pure rolling up the incline,the friction must act to oppose the tendency of slipping. As the sphere moves up,the friction acts in the upward direction to provide the necessary torque to maintain the rolling condition.When the sphere reaches its highest point and starts moving down,the direction of its translational velocity reverses. To maintain pure rolling while moving down the incline,the friction again acts in the upward direction to oppose the tendency of the sphere to slip down the incline.Therefore,the direction of rolling friction is upward during both the upward and downward motion.

$A$ solid sphere is thrown up a rough incline. The sphere rolls up without slipping and eventually comes down rolling without slipping. The direction of rolling friction in upward and downward motion respectively is ............
