PhysicsNEET 2024Collisions: elastic and inelastic

Work, Energy and Power

Two bodies A and B of the same mass undergo a completely inelastic one-dimensional collision. Body A moves with velocity while body B is at rest before the collision. The velocity of the system after the collision is . The ratio is:

  1. A.2 : 1✓
  2. B.4 : 1
  3. C.1 : 4
  4. D.1 : 2

Solution

Momentum conservation for a perfectly inelastic collision: .
