A thin ring of mass 2 kg and radius 0.5 m is rolling without slipping on a horizontal plane with velocity 1 m/s. A small ball of mass 0.1 kg, moving with velocity 20 m/s in the opposite direction, hits the ring at a height of 0.75 m and goes vertically up with velocity 10 m/s. Immediately after the collision

A

the ring has pure rotation aboutits stationary CM.

B

the ring comes to a complete stop.

C

friction between the ring and the ground is to the left.

D

there is no friction between the ring and the ground.
