Question

In a perfectly ELASTIC collision between two perfectly rigid objects?

A) both the momentum and the kinetic energy of the system are conserved. B) the momentum of each object is conserved. C) e momentum of the system is conserved but the ki conserved. D) netic en of the system is not E) the kinetic energy of the system is but the momentum of the system is not conserved.

Answer 1

The momentum is always conserved in the collision,

Energy is only conserved in elastic collisions.

(A) is correct
