Two objects bounce into each other and then repel back in the opposite direction. The momentum and kinetic energy are found to be the same before and after the collision. Which of the following is true? Two objects bounce into each other and then repel back in the opposite direction. The momentum and kinetic energy are found to be the same before and after the collision. Which of the following is true? The collision is elastic because both momentum and kinetic energy are conserved The collision is elastic because momentum is conserved and the collision doesn't depend on kinetic energy The collision is inelastic because both momentum and kinetic energy are conserved The collision is inelastic because momentum is conserved and the collision doesn't depend on kinetic energy
