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: ->->->->->->->->->->->-> :

As the automobile coasts back down to the same position it will be moving at a faster speed than when it started since it is going in the direction of gravity.
