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 race driver has made a pit stop to refuel. After refueling, he leaves the pit area
with an acceleration whose magnitude is 6.0 ms-2, and after 4.0 s, he enters the
main speedway. At the same instant, another race car that is on the speedway and
travelling at a constant speed of 70.0 ms-1 overtakes and passes the entering car.
If the entering car maintains its acceleration, how much time is required for it to
catch the other car?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F292e9c50-7804-4c6e-82b3-b960e7cd57c7%2F3d7aaa0d-10ec-45b8-9523-5684309ccc18%2Fsrgiq89_processed.jpeg&w=3840&q=75)
