If a ball hits a another ball with the same mass at rest in a perfectly elastic collision, what would most likely happen?
The two balls would swap velocities.
The first ball would keep moving but at a slower speed. The second ball would move faster.
The first ball would bounce backwards, and the second ball would move forwards.

The two balls swap velocities in perfect elastic collision.

Explanation:

The collision where the kinetic energy in a system remains constant after the collision is called elastic collision. The momentum and kinetic energy remains the same in this collision.The kind of collision in which little kinetic energy is spent due to collision is inelastic collision.The momentum is conserved. When two balls of equal mass experience perfectly elastic collision, the balls swap their velocities without any change in their kinetic energy and momentum.The perfect collision condition is difficult to obtain in practical situations.
