An automobile is driving excessively fast at a constant speed of 28m/s. An officer notices the speeding vehicle. The police officer starts from rest just as the speeder passes it, and accelerates at a constant rate of 2.1m/s2. The maximum speed of the police car is 54m/s. When the officer's vehicle reaches maximum speed, it moves at a constant speed. a. How long does the officer take to catch the speeder? XS b. What distance has each vehicle traveled? Xm c. If the police car starts is after the speeder passes it, how long does it take to catch the speeder? X S
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.
