A car gains speed at a constant rate as it moves to the right. It covers the distance between two points 60.0 meters apart in 6.00 seconds. Its speed as it passes the second point is 15.0 m/s. a) What was the velocity of the car at the first point? b) What was the acceleration of the car? c) Assuming the car began from rest and continued with this same acceleration, at what distance before the first point did the car begin?
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.
