As a train accelerates uniformly it passes successive 850 meter marks while traveling at velocities 1.5 m/s and then 15 m/s. a. For the first mark of the journey, what is the acceleration of the train in m/s sq? b. Determine the train's velocity when it passes the next mark in m/s. c. Determine the time it takes to travel the 1.7-km distance in seconds.
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.
