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: ->->->->->->->->->->->-> :
We have to assume that friction is going to act against the car as it moves up and down the incline. That being said, the car will lose energy and have less KE than PE. The car will travel to its max point when vf is 0 and therefore KE is 0. When it moves back down it will once again be opposed by friction once again losing more energy and overall, resulting in a slower speed.
