An automobile speeding at 100 km/h passes a stationary police cruiser. The police officer immediately starts to move her cruiser in pursuit. She maintains a constant acceleration uniformly of 6.0 m/s2 a. How long does the police cruiser take to catch the speeder? b. How far from the initial position does the police cruiser take to catch the speeder? c. What is the position of the police cruiser when the automobile is 50 m from the start?
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.
