In the figure here, a red car and a green car move toward each other in adjacent lanes and parallel to an x axis. At timet = 0, the red car is at x, = 0 and the green car is at x, = 218 m. If the red car has a constant velocity of 20.0 km/h, the cars pass each other at x = 43.4 m. On the other hand, if the red car has a constant velocity of 40.0 km/h, they pass each other at x = 76.7 m. What are (a) the initial velocity and (b) the (constant) acceleration of the green car? Include the signs. Green car Red car (a) Number i Unit (b) Number i Unit
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.
