A 50.0-g Super Ball traveling at 28.0 m/s bounces off a brick wall and rebounds at 18.5 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 3.45 ms, what is the magnitude of the average acceleration of
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.

Wouldnt the rebound be going in the negative direction as it is going away from the starting point? How do we know that the wall is on the left side and not the right? If the wall was on the right side, then the ball would be traveling towards the wall in the positive direction.
