In case of pure rolling, what will be the velocity of point A of the ring of radius R ? 1851 88 System of Particles and Rotational Motion Report Error A vcm B 2vcm C 2vcm D 2vcm Solution: vnet = vcm2 +vcm2 = vcm 2 WebPure rolling is a situation when there is no slipping while rolling. This can only occur when the contact point of rolling object with the surface is having zero velocity. It occurs when velocity due to translation motion exactly cancel out the velocity due to rotation motion. This will happen when (V = w x r)
