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.

A rocket-powered sled moves along a track, eventually reaching a top speed of 256 m/s to the west. It then begins to slow down, reaching a complete stop after slowing down for 1.52 s. What was the sled s average acceleration and velocity during the slowdown phase?
a. 128 m/s^2 east, 128 m/s east
b. 168.4 m/s^2 east, not enough information
c. 0 m/s^2 0, 128 m/s west
d. 168.4 m/s^2 west, not enough information
