Hi there!!!!! :DDDD

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 restagainst a tree. What is the magnitude of the ball’s displacement? 
A. 4 meters 

B. 9 meters 

C. 14 meters 

D. 45 meters

Answer: 4 meters 
The magnitude of the ball's displacement when the ball is rolled uphill with a 5 meters before it slows, stops and begins to roll back and the ball rolls downhill 9 meters before coming to rest is 4 meter. Just subtract 9 meters with 5 meters. Therefore the answer is A.
