A car traveling at a speed of 25 m/s suddenly sees the red light 40 m ahead of him. The driver takes 0.75 s to react and slows the car down at a constant rate of 10 m/s². 1. How long does it take the car to come to a complete stop from the moment the break was applied? 2. Find the total time the car takes to come to a complete stop from the moment the driver first saw the red light. 3. Determine whether the car ran the red light.
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.
