There are four traffic lights on a stretch of road and the distance between each traffic light is 300m. There is a 10-s lag time between successive green lights: The second light turns green 10 safter the first light turns green, the third light turns green 10 s after the second light does (and,thus, 20 s after the first light turns green), and so on. Each light stays green for 15 s. Having watched this sequence for some time, you understand that you can drive through the stretch ofroad at a range of constant speeds.You drive through the first light right when it turned green. What is the fastest speed that youcan drive through the stretch of road without running any red lights? What is the slowest speed?
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.
