PLEASE HELP ASAP!! An object moves 15.4 meters north and then 10.5 meters south. Find the difference between between the objects distance and the magnitude of the object's displacement. Round your answer to three significant figures.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
