A student is running at her top speed of5.0 m/s to catch a bus, which is stopped at the bus stop. When the studentis still 40.0 m from the bus, it starts to pull away, moving with aconstant acceleration of 0.170 m/s2. For how much time and what distance does the student have to run at 5.0 m/s before she overtakes the bus?
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.
