A van (with constant speed 78.3 mile/hr) passes a police car at rest. As the van is 10.0 m ahead of the police car, the police start to pursue at a constant acceleration until he catches up the van after 23.3 s. (1 mile = 1609 m, 1 hr = 3600 s) a) Determine the distance traveled by the police car when he caught the van. b) Determine the acceleration of the police 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.
