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.

starting the motion in (km /hr)
8. If the driver applies the brakes after reaching the maximum speed (189mph), to get a constant
acceleration of 4. 5m/s2
a. Max. braking distance (Assume constant acceleration)
b. Max. Stopping time (Assume constant acceleration)
c. If the driver identifies a certain hazard on the way that is 120 m away, will the driver hit the
object or not? Knowing that he was driving with the maximum speed of the car and that the
brakes were applied directly after noticing the obstacle.
