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: ->->->->->->->->->->->-> :
It is moving faster than when it began unless it comes to a stop at the exact same place that it started. As we’ve seen with the toy car traveling up an incline, the frictional force is greater while it is going up the incline. With the regular coasting car, it would follow the same pattern.
