You are to drive to an interview in another city at a distance of 300km on an expressway. The interview is 11:15 in the morning and you plan to drive at 100kph so you leave at 8 in the morning to allow some extra time. You drive at that speed for the first 100km, but then construction work forces you to slow to 40kph for 40km. What would be the least speed needed for the rest of the trip to arrive in time for the interview?
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.
