A disc is rolling on an inclined plane without slipping. The velocity of centre of mass is `V`. These other point on the disc lie on a circular are having same speed as centre of mass.
When a disc is rolling on an inclined plane. The magnitude of velocities of all the point from the contact point is same, having distance equal to radius `r`.
