A car starts from rest and moves with constant acceleration a = 2.0 m /s2 until it reaches v 26.0 m /s speed. It then continues to move with this constant speed. (a) For how long does the car accelerate? (b) How much distance is covered by the car during the time it accelerates? (c) After reaching the speed of v 26.0m /s, how much longer should the car travel until its average speed becomes v 24.0m/s?
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.
