Cneither elastic nor inelastic bodies
-
Dnone of these
Answer
Correct Answer: elastic bodies
Explanation
ConceptElastic impact implies the coefficient of restitution e = 1, so the bodies fully rebound consistent with kinetic energy being conserved in the normal direction.
ContrastIn inelastic impact (0 ≤ e < 1), bodies do not fully rebound; in perfectly inelastic impact (e = 0) they stick together.
