A toy train rolling on a straight stretch of tracks, initially going 0.31 m/s slows uniformly to 0.14 m/s in 17 s. It then speeds up with a constant acceleration of magnitude 0.068 m/s2 over a distance of 4.2 m. ii) What is its final speed after speeding up for the last 4.2 m
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.
