Vedclass · Answer

(D) When a cylinder rolls down an incline with sliding, the kinetic friction acts on the body to change its translational and rotational motion. If the initial conditions (such as initial velocity or angular velocity) are such that the friction can bring the body to the condition of pure rolling $(v = r\omega)$, then it will start pure rolling after some time. However, if the incline is not long enough or the conditions are such that the body reaches the bottom before the pure rolling condition is satisfied, it may never start pure rolling. Therefore, both possibilities exist depending on the initial parameters and the length of the incline.

If a cylinder is rolling down an incline with sliding, then which of the following is true?
