A policeman is sitting on the side of the road in his cruiser when he notices a car coming up behind him. The car has a constant speed of 20 m/s. The police cruiser accelerates from rest with an acceleration of 4 m/s2 when the speeder is 20 meters behind the cruiser. how long after the police cruiser starts to accelerate does the speeder pass it?
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.
