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.

1. Two cars start from rest in the same position and at the same instant and travel along a straight track. Car A accelerates at a rate of 6.6 ft/s2 until it reaches a speed of 90 mi/hr and then remains at this speed. Car B accelerates at a rate of 4.4 ft/s2 until it reaches a speed of 96 mi/hr and then remains at this speed.
A) to. Which car will win the 3 mile race and by how much margin.
B) What is the maximum advantage of A over B.
C) How far have the cars traveled when B passes A?
2. A car is 40 ft behind a truck, both moving at 55 mi/hr. Suddenly the truck stops slowing down at 10 ft/s2. Two seconds later the car brakes with a deceleration BC. Find the minimum value of BC so that the car does not collide with the truck.
