Directions: The following question has FOUR choices, out of which ONE or MORE are correct.
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 about its 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.
Correct answer is option 'A,C'. Can you explain this answer?

Directions: The following question has FOUR choices, out of which ONE...
Linear momentum along horizontal axis conserved
Final momentum=
As the particle is moving along the venicaldrection after collision, hence
Pf = 0,
Ring will come to rest after collision
Using conservation of angular momentum about the point doodad of the ring
Indal angular momentum,
-ve sign means direction of ‘L’ is into the plane of paper
+ ve sign means direction of ‘L' is out of the plane of paper
Indal angular momentum,
Final angular momentum about the point of contact
Hence, the ring will rotate anti-clockwise and the velocity of the point of contact is towards right. So, friction will act towards left.
