1.	A disc is rolling the velocity of its centre of mass is V_(CM). Which one will be correct?
Answer» The velocity of highest point is `2V_(CM)` and point of CONTACT is zero. The velocity of highest point in `V_(CM)` and point of contact is `V_(CM)`. The velocity of highest point is `2V_(CM)` and point of contact is `V_(CM)`. The velocity of highest point is `2V_(CM)` and point of contact is `2V_(CM)` ANSWER :A
