A car picking up speed at a uniform rate from rest passes three VECO posts in succession. The posts are 91 meters apart along the road. The car takes 10 seconds from the first to the second post, and 6 seconds from the second to the third post. Calculate: the acceleration of the car the distance from the starting point of the car to the first post the car’s velocity at each post.
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.
