6. Freight trains can produce only relatively small accelerations. a. What is the final velocity of a freight train that accelerates at a rate of 0.0450 m/s? for 7.00 min, starting with an initial velocity of 4.50 m/s? b. If the train can slow down at a rate of 0.500 m/s², how long will it take to come to a stop from this velocity? c. How far will it travel in each case?
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.
