Which of the following is/are the best example (s) of elastic collision (s) ? Explain why you chose your answer. A) A collision between two billiard balls. B) A collision between two automobiles. C) A basketball bouncing off the floor. D) An egg colliding with a brick wall.

A

Explanation:

option A is correct

the best example of elastic collision among the following is collision between two billiard balls. In collision of two billiard balls the energy lost is very little approximately zero. hence we can say that the kinetic energy is conserved. since, the kinetic energy is conserved we can say that the collision is elastic
