In perfectly inelastic collisions, the relative velocity of the bodies

Options

  1. Abefore impact is zero
  2. Bbefore impact is equal to that after impact
  3. Cafter impact is zero
  4. Dis characterised by none of the above

Correct answer

C. after impact is zero

Step-by-step solution

We know that, in perfectly inelastic collisions between two bodies, both bodies move together with same velocity after impact. Relative velocity after impact, v _ Rel = v ₁- v ₂= v - v =0
