A car is 18-meters past the entrance to a restaurant and traveling at a speed of 16 m/s when the driver applies the brakes. The speed of the car decreases with a constant deceleration of magnitude 2.3 m/s/s. How long after the driver applied the brakes will the car be 65-meters past the entrance to the restaurant? What will be the car's speed at the time in part a? How far, after the car applies the brakes, will the car come to rest?
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.
