In perfectly inelastic collisions, the relative velocity of the bodies
- A before impact is zero
- B before impact is equal to that after impact
- C after impact is zero
- D is characterised by none of the above
Answer & Solution
Correct Answer
(C) after impact is zero
Step-by-step Solution
Detailed explanation
We know that, in perfectly inelastic collisions between two bodies, both bodies move together with same velocity after impact. \(\therefore\) Relative velocity after impact, \(\mathbf{v}_{\text {Rel }}=\mathbf{v}_1-\mathbf{v}_2=\mathbf{v}-\mathbf{v}=0\)
