Truly elastic collisions are achieved only with:
ASteel blocks on ice
BCarts with springs
CBilliard balls
DSubatomic particles
Answer & Solution
Correct answer: D. Subatomic particles
1. Macroscopic collisions lose some energy to heat and sound.
2. Only subatomic particles collide truly elastically.
3. Steel on ice is nearly elastic.
