A typical automobile coasts up a typically paved incline, stops, and coasts back down to the same position.

When it reaches this position, is it moving faster, slower or at the same speed as when it began? Explain

answer/question/discussion: ->->->->->->->->->->->-> :

I believe it will be traveling at the same speed at which it began. It has an initial velocity going up the hill, slows down and finally stops, and then progresses back to the starting point so I feel that due to the acceleration of gravity experienced and the same factors as going up the hill that it will return to the initial velocity.
