A motorist traveling with a constant velocity of 30 m/s passes a school-crossing comer, where the speed limit is 20 km/h. Just as the motorist passes, a traffic officer on a motorcycle stopped at the comer starts off in pursuit with a constant acceleration of 2.0 m/s?. How much time elapses (in seconds) before the officer catches up with the motorist?
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.
