1.	Two identical balls of mass M and mradius R each are placed on a frictionless plane. One of the balls is at rest while the second moves at a velocity v towards the first ball tangentially. The two balls stick together on collision. Then
Answer» the speed of the centre of mass does not CHANGE because of the collision the ANGULAR velocity of the system after the collision is `(5v)/(14R)` the KINETIC ENERGY of the system after the collision is `3/7"Mv"^(2)` someenergy is lost during the collision. Answer :A::B::C::D
