## michelle10 2 years ago momentum is always conserve in a collision between two objects.If the collision also conserves kinectic energy its called elastic .if not its elastic.2 objects A & B collide and stick they encounter a 3rd object C. which statement is true? 1.Both collisions were elastic objects because momemtem is conserved 2.At least one of the collision s was in elastic 3.Both collisions were inelastic 5.At least one of through collisions was elastic

If not its inelastic .Sorry

If two things stick together, they lose their kinetic energy (not moving anymore). If they lose their kinetic energy, by definition it has to be inelastic. Think of it like a rubber band (made of elastic), where when you stretch it it will go back to its original size. But if you are playing with silly putty and you stretch it out, it is inelastic because it does not return to its original form.

Ok so whsts the best answer ! PLZHELP

Did you read what I said? The answer is in the paragraph I wrote. Do you understand the concept of elastic and inelastic?

Im thinking #3 Inelastic?

Yes.
