An express train passes through a station that is 212 m long. It enters with an initial speed of 22.5 m/s and decelerates at a rate of 0.13 m/s2 as it goes through. During what time interval, in seconds, is the front of the train within the station? If the train is 120 m long, how long, in seconds, after the front of the train enters the station does the end of the train leave the station? What is the velocity of the end of the train as it leaves in m/s?
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.
