A car is speeding at 25 m/s (~56 mi/hr) in a school zone. A police car starts from rest just as the speeder passes and accelerates at a constant rate of 5 m/s2. • a)When does the police car catch the speeding car? ● b)How fast is the cop car moving when it reaches the speeder? ● c)What distance has the cop car traveled when it reaches the speeder? •How fast is the police car traveling when it is 25 m behind the speeding 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.
