a car bumps into a garbage can and pushes it down the driveway. why is this considered an inelastic collision?

Looking at the fact that there was no change in the  velocity of the garbage can, then there is an inelastic collision.What is an elastic Collison?An elastic collision has to do with the kind of collision in which there is a conservation of  both kinetic energy and momentum. This implies that there is a change in the velocity of the both objects. Three must be one that impacts an increase in velocity to the other object and this makes the other object to move faster.Let us consider a situation in which a car bumps into a garbage can and pushes it down the driveway. We have to note that the garbage can does not get an acceleration because it just remains where it is to indicate that there is no change in the velocity of the object.Since the velocity of the object did not change, we can then say that what we are having is just an elastic collision.Learn more about collison:https://brainly.com/question/14992935#SPJ1
