A car accelerates from rest to 48 m/s in 6 s. a. What is the average acceleration of the car? b. How far did the car travel during this time period? c. Imagine if the car was initially 800m west of city xyz moving east at 20 m/s. At this instant, the car begins to accelerate at a rate of -5m/s^2 for 20 s. Calculate the final position and displacement of the car.
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.
