5. A vehicle is at rest at a traffic red. A truck moving at a constant velocity of 12 m/s gets to the traffic light when it just turn green and continue moving with this constant velocity. The car driver whose reaction time is 1s realizes that the truck is leaving and accelerates uniformly at 4 m/s? to meet up with the truck. How long does it take for the car to meet up with the truck?
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.
