A ball is rolled uphill a distance of 5 meters before it slows stops and begins to roll back. The ball rolls downhill 9 meters before coming to rest against a tree. What is the amount of displacement?

The total displacement of the ball is the difference between the uphill distance (5 meters) and the downhill distance (9 meters), as displacement considers the final position relative to the initial position. Therefore, the displacement of the ball is 9 meters (downhill distance) - 5 meters (uphill distance) = 4 meters.
