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

A

the ring has pure rotation about its stationary

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

Text Solution

Verified by Experts
