Kate Jenkin's Reckless Driving. After learning that she's very fast on foot, Kate decides she wants to be very fast in a car. At 2:25pm, she runs out of the school and gets into her car. Initially at rest, the car speeds up to 39 m/s in just 3.9 seconds a) What is her acceleration? b) How far does she travel in those 3.9 seconds?
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.
