At the instant a traffic light turns green, the starts ahead with a constant acceleration of 1.44 m/s2. At that moment a truck traveling with a constant velocity of 40mph overtakes and passes the car. (1 mi = 1.6 km) a) Calculate the time necessary for the car to reach the truck b) Calculate the distance beyond the traffic light that the car will pass the truck c) determine the speed of the car when it passes 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.
