Two bodies A and B of same mass undergo completely inelastic one dimensional collision. The body A moves with velocity v₁ while body B is at rest before collision. The velocity of the system after collision is v₂ . The ratio v₁: v₂ is

Options

  1. A2:1
  2. B4:1
  3. C1:4
  4. D1:2

Correct answer

A. 2:1

Step-by-step solution

It undergoes completely inelastic collision Using conservation of linear momentum Initial momentum = Final momentum aligned & m v₁=m v₂+m v₂ & m v₁=2 m v₂ & v₁ v₂ = 2 1 aligned
