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: ->->->->->->->->->->->-> :
The final velocity when the car comes back to the original position should be the same as the initial velocity when the car started up the incline. This is because only the initial and final velocities are reversed in the problem; the acceleration and time interval should be the same. This is for an ideal situation, if there were friction to take into account, then the final velocity would less than before.
