A subway train has to travel a distance of 1800 m until it stops at the next station. The train starts from rest and accelerates at a rate of 1.60 m/s2 for 15.0 s. It then runs at a constant speed for some time and finally slows down at a rate of 4.0m/s2 until it stops at the next station. How long did it take to reach the next station?
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.
