You are talking with a cell phone while trailing a police car by 20m; both ypur car and the police car traveling at 100km/h. Your conversation diverts your attention from the police car for 2,0 s. At the beginning g of that 2,0s the police officer begins braking suddenly at 6m/s2 . A- What is the separation between the two cars when your attention finally returns? Suppose that you take another 0,3 s to realize your danger and begin braking. B- If you too brake at 6m/s2 , what is your speed when you hit the police car.
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.
